A Jeep grille that rides on top of a straw, seven slots and all.

Design by Morganja

A dog's head that sits on top of a straw, ears up and nose forward.

Design by Morganja

A lid that snaps onto a standard can and seals it up again between sips, and doubles as an opener when you slip it over the tab and tilt. It is the wider, support-free version, and it fits both the slim and the fat cans the designer built it around - European 202 cans, so if yours is a different can it is worth a quick measure. Light sanding on the slots is the only finishing it asks for.

Design by MakerShed

A clip-on egg separator: crack an egg into the channel and the white runs through while the yolk stays put. 3.6" long, printed in one piece, and it sits on the rim of a cup or a bowl.

Design by user_4069524941

A pair of arrow earrings, each with a coiled shaft, a small loop at the tip for the hook and a heart-shaped flight. They print flat and weigh well under a gram for the pair, so they want hooks or studs fitted afterwards. Each is 2.1" by 0.7". The "+ hooks" option arrives with the metal hooks fitted; the plain one is the printed plastic on its own.

Design by TinkerTogether

An impossible passthrough built as a pyramid: the parts pass through one another and no amount of turning lets them go. 2.8" tall, about 21 g of plastic.

Design by BeninManc

A one-piece beard comb with rounded teeth that glide through without scraping. Small enough to live in a jacket pocket, and it prints without supports. The solid band above the teeth can carry a name, cut into the surface rather than raised, because a comb lives in a pocket and raised letters are the first thing to wear off: type the name while you are adding it to the cart, up to 12 characters, +$5. A personalized comb is cut to order, so it is paid online rather than reserved for cash at pickup. Leave it blank and it comes exactly as the photos show it.

A gyro fidget spinner: three curved rings interlock around a centre post and whirl as one, so it prints in a single piece with no bearings and no assembly - just flick it and go. The rings are loose in their track out of the printer, which is the part that takes a few tries to get right and the reason this one gets measured before it ships.

A printable reading ruler with an integrated bookmark pointer. The pointer holds your line while you read and marks your place when the book closes - pick the length that suits your book.

Two spirals in one print: an outer shell that twists one way and a core that twists the other, turning past each other as you fiddle. Printed in a single colour it reads as one tapering cone; give the shell and the core a colour each and the two spirals separate in the eye as they turn, which is what the designer's own pictures show. The profile that prints it is 0.2 mm layers, 3 walls, 15 per cent gyroid infill, PLA, no supports, standing upright exactly as supplied.

Design by NerdHerder

A pencil holder wearing a puffer jacket: quilted panels all round, with a zip, a collar and sleeves running up the sides. It holds pens, pencils, markers, brushes or small tools, and it is sturdy enough to be knocked about a desk. About two hours of printing, and the quilted panels take filament colours well - solid winter colours, pastels, or something loud.

Design by Sitsero

A low-poly Labrador, faceted like cut stone, standing with its head up: the low-poly build keeps it light enough to print and lets it catch the light along the facets. Two sizes - the big one at 4.7" tall and a pup at 2.4" - each printed in one piece.

Design by CreaitivityStudio

A plump bee that clips onto the top of a straw, wings raised and its stripes cut deep enough to read across a table. It suits the 10 mm Stanley straws, is 1.6" by 1.5", and prints in one piece with no supports.

Design by Morganja

A Spartan helmet in profile, crest and all, 2.2" tall, with a loop at the top so it hangs as a pendant or swings on a keyring. It prints flat in one piece, which keeps the crest and the cheek guard crisp.

Design by OrangeSs

A bowl for rinsing rice: the water swirls through the grain and pours off the side while the rice stays put, so you stop losing half of it down the sink. Two sizes - 6.9" across and a smaller 4.8" - each printed in one piece, with the drain holes and the pouring lip part of the bowl.

Design by ValeraPerinski

A hard hat that goes on a keyring - the dome, the brim and the little ridge down the middle, printed in one piece with a hole through the top. 1.5" across, and it works as a key tag or a desk charm.

Design by astavr

Four dinosaur cookie cutters with matching stamp inserts - press the stamp for the details, cut the outline, bake. Each cutter is about 3" across, and the set is four different animals.

Design by Merilno3D

An impossible passthrough shaped like an hourglass: two halves that turn through each other and stay locked together. 2.8" tall, about 24 g of plastic.

Design by BeninManc

Wet gloves dry upside down on six tapered, vented posts, over a 4x10 inch floor vent. A glove's cuff slides over a post so warm air from the register goes up through the post and through the glove, drying the inside as well as the out - which is the part that stays wet. The tray is a colander: a lip catches a dribble of water, and a grid of drain holes lets the air up and the water down, and each post drains through its own cup. Bottles and cups fit the posts just as the old stand's did. Sized to sit inside a 4 by 10 inch register, printed in one piece with no supports and nothing to assemble. The photo is a render of the printable model - real photos of the print go up once the first batch comes off the printer.

A phone stand with a woodgrain surface that all but disappears behind the phone, so what you see is the screen standing on the desk rather than the stand holding it. A deep groove with a lipped front edge takes a phone upright for video calls or on its side for standBy and night-clock mode, and it fits anything from a small handset up to a Pro Max. Printed in PLA at 0.2 mm layers, 15% infill, no supports. It is designed for a wood-fill filament, which gives it the grain it is named for, though any matte colour prints just as well. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by M_LAB

A mini hockey stick for your keys, printed flat in one piece and shaped like the real thing: a shaft that tapers, a blade turned off it at the lie a real stick uses, a heel that rounds into the shaft and a toe that narrows and leans back. The name is cut into the blade along its length, where a stick carries its brand, and roxium.ca is cut along the shaft underneath - both personalized rather than raised, because a keychain gets rattled around in a pocket and raised lettering wears off first. Type the name you want while you are adding it to the cart and it is cut for you - up to 10 characters, +$5 a piece, charged on top of whatever the stick costs, the volume rate included. A personalized stick is cut to order, so it is paid online rather than reserved for cash at pickup. Leave the name blank and it comes with ROXIUM on the blade. The picture is a render of the printable model - real photographs of the print go up once the first one is cut.

A heart that sits on top of a straw, wide and low, catching the light as the cup moves. Shown as a render, not a photo.

Design by Morganja

A coffee cup for a keyring, complete with a lid and a sleeve, small enough to disappear in a pocket and clear enough in shape to read at a glance. 0.8" across and printed in one piece. Shown as a render, not a photo.

Design by Tuscarora Tech

Six dog charms with a bit more detail in them - a bone, a ball and a few breeds, each cut in relief. Pick the one you want: every charm has a hole at the top for a keyring or a chain, prints flat, and measures about 2" by 2.4". Shown as a render, not a photo.

Design by dominator334

An elephant charm in flat relief, trunk curled, with a hole at the top for a keyring or a chain. Shown as a render, not a photo.

Design by dominator334

A ghost bookmark: a flat spectre that hooks over the page, thin enough not to splay the spine. There are seven of them in the file, each a slightly different ghost, so pick the one you want - about 1.2" by 4" and printed flat. Shown as a render, not a photo.

Design by PrintcessJacqueline3DDesigns

A clicker keychain with four buttons that press and click, printed in place so nothing needs assembling. Shown as a render, not a photo.

Design by Print3DFamilyFidgets

Candle holders that let the light out through the walls: a Voronoi web of gaps and ridges so the flame - a battery tealight, never a real one - glows through the whole shell rather than out of the top. The set is three holders, three diffusers and the base plate that carries them; print the holders in matte black and the diffusers in white, which is the pairing the designer built it around, and a single holder works just as well on its own. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by DueMakers

A low-poly heart, faceted like cut stone: the low-poly build keeps it light and lets it catch the light along the facets, and it stands on its own on a shelf. 3.4" wide, printed in one piece. Shown as a render, not a photo.

Design by Creaitivity Studio

A six-can holder that spins: six runners hold the cans and the base turns, and it uses very little filament for its size. Four pieces. Shown as a render, not a photo.

Design by JEP0405

A cat curled into a charm, cut as a flat silhouette with a hole at the top for a keyring or a chain. Shown as a render, not a photo.

Design by dominator334

A DAD heart gyro fidget: a heart with DAD cut through it, mounted so it spins in the frame when you flick it. 1.8" by 2.2", printed in one piece with the pin already in place. Shown as a render, not a photo.

Design by LangHjornArt

A star that spins: the points are cut so it turns on its axis in the hand and keeps turning. Shown as a render, not a photo.

Design by CreaitivityStudio

A bow that clips onto a straw: the straw runs through the middle and the bow sits above the lid. Shown as a render, not a photo.

Design by Morganja

Love hearts, one letter at a time: A to M, each a heart-shaped charm with the letter cut into it, so a name or a message is spelled out a charm at a time. About 1.6" by 1.6" each, with a hole at the top for a keyring or a chain. Shown as a render, not a photo.

Design by dominator334

A little bear holding a heart, printed in one piece with the heart standing proud of its chest. Shown as a render, not a photo.

Design by davide7seven

A thin blade for digging the lint out of a phone's charging port, with a hook at one end and a flat scraper at the other. 34 mm long and a fraction of a gram, so it prints three at a time in a minute - one for the desk, one for the car, one to lose. Shown as a render, not a photo.

Design by eclien

Twenty-six dog charms, each cut with a different dog in relief so it reads at a glance on a keyring or a necklace - the designer's three sets, in one listing. Pick the dog you want: every one has a hole at the top for the ring or the chain, prints flat with no supports, and measures about 1.4" by 2.4". Four or more of any mix come at the bulk rate. Shown as a render, not a photo.

Design by dominator334

A beer crate for batteries, scaled down to sit on a shelf: stacked sides, a slotted top and a handle you can actually lift it by. Holds a row of AA or AAA cells - pick which, they are separate crates. About 2.7" long. Shown as a render, not a photo.

Design by JSBallpython

A pair of lips that sits on top of a straw: the straw passes through the middle and the lips ride above the lid, catching the light as the cup moves. It suits the 10 mm Stanley straws, is 3.9" tall by 2.2" across, and prints in one piece. Shown as a render, not a photo.

Design by Morganja

A hexagonal tube cut into one continuous spiral, so it springs and flexes in the hand and the turns of the helix roll past each other under a thumb. It prints as a single piece and needs no assembly, and it stands 2.8" tall by 1.3" across. Shown as a render, not a photo.

Design by NerdHerder

A cap that turns a jar into a fruit washer: fill it, shake, and the water spins the berries clean instead of bruising them. The cap and its inner piece print together in one go - size L fits a standard wide jar. Shown as a render, not a photo.

Design by ValeraPerinski

The classic folded awareness ribbon with a keyring loop at the top, printed flat so the fold reads cleanly on both faces. It is 2.5" long by 1.4" wide and prints in whatever colour you choose. Shown as a render, not a photo.

Design by Miss3DP

A desk caddy printed in one piece: a raised back that stands a phone at a reading angle, a round well for pens, and a square tray for a watch, keys or a card, with a slot for a charging cable to pass through. It is 7.1" wide by 3.5" deep. Shown as a render, not a photo.

Design by Maker76

A flat key tag that holds the key by its bow rather than its ring, so it lies flat in a pocket and does not rattle. 2.2" long, about 1 g of plastic, printed in one piece. Shown as a render, not a photo.

Design by Katejot2017

A planetary gear set printed in place: six small gears mesh between a sun gear and a toothed ring, so turning any one of them turns all the rest. It is 2.5" across and prints as a single piece with nothing to snap together. Shown as a render, not a photo.

Design by HurtTree

Ten layered fidget discs off one plate - each about 3" across, each with its own cut-through pattern and its own way of spinning and clicking. Pick the design you want; the picture on each chip is that disc. Shown as a render, not a photo.

Design by PenguinPrototypes

A kitchen roll holder with a weighted base: the disc takes sand or coins, so the roll stays put while you pull one sheet off with one hand. 9.1" tall, printed as a base and a post. Shown as a render, not a photo.
