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.

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 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 push-fit cover for the Tesla Cybertruck's front tow hook recess, so the bumper reads as one clean line instead of an open slot. It clips in with a lip at each end and no hardware. Choose the material: PETG shrugs off sun and road salt, PLA is the everyday version at the same price. The prototype in the video carries the name "Shadowfax" embossed into its face - that was that truck's own, and yours can have a word of its own cut the same way: type it while you are adding it to the cart, up to 12 characters, +$10. A personalized cover is made to order, so it is paid online rather than reserved for cash at pickup. Leave it blank and the face is plain.

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 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 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

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

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.

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 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

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 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 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 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

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 dog's head that sits on top of a straw, ears up and nose forward. Shown as a render, not a photo.

Design by Morganja

A fold-over bag clip in one piece, with nothing to assemble: two slim bars on a round hinge, and a hook at the far end that shuts them. Roll the bag's neck over, slide it in side-on between the bars, and press the hook home - the knob at the end of the curl rides over the upper bar's tip and drops into the groove cut behind it, so the clip is held shut by the hook and not by the moulding. Flex the curl back off the tip and it opens again. The hinge is a disc with a hole through it, so the clip hangs on a keyring or a cup hook when it is not on a bag. It prints flat as a single piece with no supports, and PLA holds fine while PETG survives the dishwasher and takes more flexing. The picture is a render of the printable model - real photographs of the print go up once the first batch comes off the printer.

A graduation cap and gown on a keyring: the mortarboard tilted over the gown, with a class year or a name across the front on the version the designer included for it. It hangs flat and reads clearly from a distance, which is what a keepsake for a graduate wants to do. Printed as one tag with the layered faces so the cap, the gown and the lettering each read separately. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by Cardboard Junkie

Two bands that print as one piece: the finned outer ring's ridge sits in the inner band's groove, so it is locked on but free to spin, with no bearings and nothing to assemble. The groove is a BALL RACE - a circular channel, with the ridge as the same circle held 0.4 mm off it - so the surfaces the two parts face each other across are vertical, which is what lets it print in place and still turn. The ring is 27 mm across and stands 7 mm, and the fins are trapezoids: wide where they join the sleeve, narrow at the tip, so nothing on it is a blade waiting to be knocked. It comes in three sizes, 16.5 mm (US 6), 18.2 mm (US 8) and 19.8 mm (US 10) across the finger hole, all at the same price, and the download is a 3MF with a plate for each, so you can print whichever fits - or all three. Print it with a brim and z-hop switched on: a small ring has a small footprint, and z-hop keeps a moving nozzle clear of what is already printed. The STL on its own is the smallest of the three. 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 Jeep grille that rides on top of a straw, seven slots and all. Shown as a render, not a photo.

Design by Morganja

A bag peg that works like a clothes peg: two arms on a printed pin, so the ends you squeeze and the jaws are on opposite sides of the pivot, and squeezing opens the jaws. A disc on the upper arm turns inside a socket on the lower one, printed in place with a quarter of a millimetre of air round it - press the peg open and you can feel the pin move. Behind it one strip sweeps round and back to the other arm as a scroll you can see through, and that scroll is the spring: it closes the jaws and it is what you feel working when you squeeze. The mouth is a square-wave channel cut through both jaws at once, so the two sets of teeth come from the same cut and interlock - every tooth of one jaw stands in the hollow of the other - and along the outside of each arm, where a thumb goes, a row of sawteeth bites into the silhouette so the peg does not slip in your hand. It prints flat as one piece, no supports, nothing to assemble. PLA holds fine; PETG survives the dishwasher and takes more flexing. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

A keyring that opens without a metal split ring, printed as one piece with nothing to assemble. The flat band is broken once, and across that break the two ends lap through the ring's own thickness - the socket keeps the lower half, the near end the upper, with a quarter of a millimetre of air between them - so the finished ring reads as one band with a hairline in it rather than two pieces butted together. What holds it shut is the gate's own end, narrowed to a tongue: the band's inner and outer edges step down either side of it, and the tongue carries a rounded bump underneath that sits in a seat cut into the socket. Flex the ring apart and the bump rides up its own rounded side, which is a detent and not friction; let go and it drops back in. The tongue is relieved with a round hole at its root, because that is where it bends when you press it up to open the ring. Flex it, thread your keys on, squeeze it shut. The picture is a render of the printable model - real photographs of the print go up once the first batch comes off the printer.

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

Five heart shapes, each layered front to back so the colours read as depth: black sits at the back as the outline and the two layers in front are yours to choose, so one colour is the simplest and three makes it pop. Pick the shape you want - each is about 1.6" by 1.5", with a loop for a keyring or a chain. Shown as a render, not a photo.

Design by dominator334

A print-in-place bag clip: the hinge prints shut and then works, so there are no pins and nothing to assemble. 3.2" long, 1.2" wide. Shown as a render of the printable model, not a photograph.

Design by printerforge

A reading guide that frames one line at a time so the page cannot swim: 5.1" x 1.4", 1.4 mm thick, light enough to leave in a book. Kept for kids learning to read, and for anyone whose attention slides down a full page. Shown as a render of the printable model, not a photograph.

Design by fgiancarelli

The 2 to 9 times tables on one flat plate, 5" x 3.6" and 1.6 mm thick - a card that lives in a pencil case rather than on a screen. Shown as a render of the printable model, not a photograph.

Design by kot1199

A modular hydroponic tower printed as twelve parts: a base, the column that stacks, five growing cups and the plates that close the sides. The column is 220 mm across and 128 mm tall, each cup 55 mm. The modules come apart, so a tower can be built one section at a time and taken down again. Shown as a render of the printable model, not a photograph.

Design by alexlluch

Design by helder.bernardo

A squeezer that slides up the tube as it empties: the roller presses the paste forward and the key at the end hooks over a rail so the tube hangs. 2.9" long, printed in one piece with the edges rounded so it does not catch on the shelf. Remixed by Weisnetde from two earlier squeezers, all under the same licence. Shown as a render, not a photo.
