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 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 skeleton printed as a chain of flexing segments, rib cage and all, so it dangles, swings and rattles about. 3.1" long, printed in one piece and only a few grams of plastic.

Design by Max

A skull with flat faceted planes rather than curves, with the top of the cranium hollowed out for a small plant or a succulent. 4.3" tall, printed in one piece - a Halloween pot that stays on the shelf in November.

Design by R3DPanda

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

Design by PrintcessJacqueline3DDesigns

Design by UncleFlappy

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.

Design by 3dprinting

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.

Shown as a render of the printable model, not a photograph.

Design by Jerryie

The picture is a render of the printable model, not a photograph of a finished print.
