Two strands twisted around each other into a pen stand: a double helix about 22 cm tall on a 14 cm square base, printed in one piece with nothing to assemble. Pens drop into the gaps between the rungs and lean out along the twist, so a handful of them fan apart instead of clumping together in a cup - and the base is wide enough that a full stand does not tip. Empty, it is a desk ornament rather than a mug with pens in it, which is most of what a pen holder does all day. Printed in PLA at a 0.2 mm layer, about 34 g of plastic.

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 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 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.

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 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 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 hanging books-read counter: a sign with a row of numbers that slide into it, so the count can be moved along as the year goes. It is two plates - the sign with one of each number, and a second sign with the numbers again so the count can pass ten - and either can be bought on its own. Shown as a render, not a photo.

Design by ZHeights

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

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.

Design by What3d

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 phone stand that folds out of a keychain: the plate swings up and the phone leans back on it, and folded away it hangs on your keys. Shown as a render, not a photo.

Design by musielovsky

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 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 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 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

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.
