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.

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 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 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 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

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

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 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

Design by dominator334

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 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

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

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 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

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

Design by Wilykid

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.

Design by Badger Sound Forge

A pair of eighth notes, each an outline rather than a filled shape, so they stay light on the ear and catch the light along the stem. Each is 20 x 22.7 mm and 2 mm thick, with the hole in the note head for a hook, and they print mirrored so the two notes sit opposite each other. Shown as a render of the printable model, not a photograph.

The Thinker, sitting on a plinth with his chin on his fist and a pair of glasses resting across his knee: 101 by 141 mm and 114 mm tall, printed in one piece as a desk glasses holder. The pose is what does the work - a pair sits in the crook of the arm and the knee, so it is always where it was put.

Design by Abz

A dragon printed as a chain of flat segments joined by print-in-place hinges, so the body ripples along its length and lies straight when it hangs still. It is 59 mm nose to tail and 8 mm deep at the head, prints in one piece with no supports, and a pair is two dragons. Shown as a render of the printable model, not a photograph.

Design by tomo3D

A modular glasses stand: a round 143 mm base with a spindle, a post that carries two long arms, and a cradle that stacks on the spindle, so two pairs or a shelf-full can be kept upright and out of the way. The arms take frames by the bridge and the base is heavy enough not to tip when one pair comes off.

Design by Rockthered

A daisy with eight rounded petals and a raised centre, 35.6 mm across and 3 mm thick, printed with a matching stud so the flower sits on a post rather than dangling from a hook. The plate holds four flowers and four studs, which is two pairs; a pair is a flower and a stud for each ear. Shown as a render of the printable model, not a photograph.

Design by mhumphries1973

A filigree arch: a curved band of scrollwork with the spaces cut right through, so it reads as lace from the front and sits like a crescent against the ear. Each is 26 x 34 mm and 2.3 mm thick with the hook tab at the top, and the pair is mirrored. Shown as a render of the printable model, not a photograph.
