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.

A set of gear examples for teaching - the gears and the pins that hold them, printed as one plate, each gear 80 mm across. 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.

A plain fidget spinner with no ornament on it at all: a body, three arms and a bearing seat in the middle. Five sizes come off the one plate, from a 1.6" one that fits in a pocket up to a 2.7" one, and the plate also carries the grips that go in the bearing seat. Pick the size you want - each is printed as one piece. Shown as a render, not a photo.

Design by MakerShed

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.

A pencil that bends: the barrel is printed as a chain of flexing segments, so it folds in your hand and springs straight again, and it still looks like a pencil with a point at one end. 4.8" long, printed in one piece. Shown as a render, not a photo.

Design by TinkerTogether

A cactus that clicks: the body snaps onto a keyboard switch, so the whole cactus is the button and the click comes from the switch inside it. Four designs, sold one at a time - pick the cactus you want, about 1.3" tall, and it prints in two pieces that snap together without glue. Shown as a render, not a photo.

Design by UKSTL

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 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.

A textured clicker with a body and a set of button caps: the caps press into the body and click under a thumb, and the spare sizes in the set let you choose how stiff it feels. 2.6" long, printed in one go. Shown as a render, not a photo.

Design by ArmadilloFDM

An inner cone passes right through an outer one and neither of them comes apart - that is the whole trick, and it prints as a single piece. Roll it in your hands and the two bodies slide past each other, which is the part that keeps fingers busy. Printed in two colours the cones separate in the eye and the pass-through reads as impossible; printed in one it looks like a solid cone until it moves. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

A glasses rack that lives on the wall: six cradles in a row on one 210 mm plate, 22 mm deep, so six pairs hang out of the way of a counter or a bedside table. It prints as one piece with nothing to assemble, and the arms take wire or plastic frames by the bridge. Designed by Matthew and printed under Creative Commons Attribution 4.0 (CC BY 4.0).

A snake, printed flat as one piece: 9.8" from nose to tail, no supports anywhere, and off the plate in about an hour by its designer's own estimate. It prints lying on the plate, so the whole thing is one layer stack rather than a tower that can topple. Shown as a render, not a photo.

A 3x3 clicker pad: nine keys on one printed body, each on its own spring, so the whole thing clicks under a thumb like a tiny keyboard. 2.6" square, printed in one piece with nothing to assemble. Shown as a render, not a photo.

Design by Print3DFamilyFidgets

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 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.

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 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 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 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

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 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

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 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 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 bit holder that clips to a Ryobi ONE+ battery: the mount takes the loose bits you are using and keeps them on the drill, so they travel with the tool rather than in a pocket. 2.1" long, printed in one piece. Shown as a render, not a photo.

Design by Terrain 6

A ruler that folds: nineteen 160 mm segments that hinge end to end, plus the two end caps, so it measures a room and then folds down to a pocket. The full set is 19 segments; the smaller option is the same design at 70 per cent, which is the one for a desk drawer. Shown as a render, not a photo.

Design by PenguinPrototypes

A workshop set of ISO 4017 hex-head screws in M3, M4, M5, M6, M7, M8 and M10, each size on its own plate, so you print the sizes you need and keep a jar of spares. The whole set is seven plates and about 55 g of plastic; the M10 is 2.8" long. Shown as a render, not a photo.

Design by Jerryie

A frog that jumps: press its back and it springs off the table, and the pond bowl catches it. Pick the frog on its own or the bowl with it - the bowl is 5" across, and three frogs fit on one plate if you want a set. Shown as a render, not a photo.

Design by Niski

Shims for levelling a cabinet, packing a hinge or shimming a door frame. One plate is four shims - 42 x 89 mm, one each at 1 mm, 2 mm, 3 mm and 5 mm thick - so you pick the thickness that squares the job up instead of stacking paper. Shown as a render, not a photo.
