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

The little tool for pulling the PTFE tube out of a Bambu A1 hot end without taking the printer apart - slot it behind the collar and lever. 1.7" long, printed in one piece in a minute or two. Remixed by R3DPanda from their own earlier version with a handle.

Design by R3DPanda

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 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 clip that holds a cable or a rope flat against a wall, in three sizes for different thicknesses. Each one is two parts that snap together - no supports, no screws - and the file prints all three sizes on one plate.

Design by GiskardReventlov

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 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 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 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

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 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

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

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

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

A hose clamp you print instead of buying: a ring with a screw lug that tightens onto a hose or a duct. Four sizes, measured across the clamp - 33 mm, 40 mm, 60 mm and 88 mm - each printed in one piece. Shown as a render, not a photo.

Design by inhabitworker

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.

Design by MicahW3D

A hexagonal fidget that prints flat in a few minutes and clicks between your fingers - no supports, no assembly, no settings to tune. 2.0" across. Shown as a render, not a photo.

Design by LangHjornArt

A fridge egg dispenser: eggs roll down a ramp and out of the front one at a time, so the oldest is always the next to come out. 9.7" long and holds a dozen, printed in three pieces - the ramp, the body and the front cup - with no supports. Shown as a render, not a photo.

Design by specialman

A 608 bearing that prints already assembled - the races, the balls and the cage all come off the plate as one piece, and it turns as soon as you break it free. 22 mm across, 7 mm thick, the size a fidget spinner or a skate wheel takes. Shown as a render, not a photo.

Design by Jerryie

An upright organizer for the utensils that live on the counter: compartments of different heights, a flat back to go against a wall, and a base wide enough that a ladle does not tip it. 8" long, printed in one piece. Shown as a render, not a photo.

Design by lunatiic

A ball that screws into its own cage - the thread holds it, and it spins from one end to the other without ever coming free. 3.9" tall, printed in place in two pieces that come off the plate already assembled. Shown as a render, not a photo.

Design by Elaak

A holder that stands cutlery up in a drawer or on a counter, with slots for forks, knives and spoons and a low front so you can see what you are reaching for. 5.9" long, printed in one piece. Shown as a render, not a photo.

Design by Alex

A shelf that hangs under a shelf: it clips over the front edge of an existing board and gives you a second tier in the gap, for mugs, spice jars or a router. 6.9" wide, printed in one piece. Shown as a render, not a photo.

Design by PanteraRuber

A rest for a wooden spoon: the bowl sits in the cradle and the handle lies over the rim, so the drips land in the holder instead of the hob. 4.7" across, printed in one piece. Shown as a render, not a photo.

Design by Jirka108

Four wedding cutters with stamp inserts - the ring, the cake slice and two more - for biscuits at an engagement or a hen do. About 3" across each, and the same set cuts playdough for the small guests. Shown as a render, not a photo.

Design by Merilno3D

A flat organizer that divides a kitchen drawer into compartments - it lies 2 mm deep, so it adds dividers without eating the depth of the drawer. 9.6" across, printed flat in one piece. Shown as a render, not a photo.

Design by Nix3D

An impossible passthrough wound as a spiral: the helical parts turn through each other and hold, printed in one piece. 2.8" tall, about 29 g of plastic. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by BeninManc

A mini golf hole for the desk: a printed course board with the hole and a rock surround, a club and a ball, all printed flat. 8.7" x 7.2", about 62 g of plastic for the set. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by MoltenPlastic3D

A stackable glasses stand: a fin that the cradles slide onto, so the tower grows to whatever height the collection needs. The cradles come in three widths - 67, 77 and 87 mm - and each holds one pair nose-down by the bridge, which suits slim readers and deep sunglass frames alike. The plate prints a whole tower's worth of parts, 167 by 199 mm laid out as the designer arranges it.
