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 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 oakliz27

A skeleton with print-in-place hinges at the shoulders, hips and knees, so the arms and legs swing as it moves and it settles back into a dangle when it stops. It prints as one piece with no supports and no assembly, 44 mm long, with a hole through the skull for a hook. Order a pair and you get two skeletons. The "+ hooks" option arrives with the metal hooks fitted; the plain one is the printed plastic on its own.

Design by tomo3D

Design by PrintcessJacqueline3DDesigns

A two-prong hair pin that holds a bun without a single elastic - the forks flex, so it grips and then lets go. Two lengths: 4.5" for fine or shoulder-length hair and 5.9" for thick or long. Printed flat in one piece, in one colour or two. Shown as a render, not a photo.

Design by riverbed

A round spider web in a ring, with every strand cut through so the web is open and a spider sits in the middle of it. Each is about 44 x 48 mm and 2.2 mm thick, with a loop at the top for a hook, and both webs print together as one piece. Shown as a render of the printable model, not a photograph.

Design by UncleFlappy

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

Six coasters shaped like leaves, 70 mm across and 3 mm thick, each with a different vein pattern. Printed flat with no supports, and thin enough to stack in a drawer. Shown as a render, not a photo.

Design by Cy-Bea

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

Design by Mosselini1

A hand rising out of the ground with its fingers curled around a candle - the fingers grip an LED tealight, so the light comes out between them. 5.2" across, printed in one piece; a 46 mm version for a bigger candle is on file. Shown as a render, not a photo.

Design by PentillyCrafts

A small ghost holding a tealight: the flame glows through the shell and out of the eyes, so the whole figure lights up. 3" tall, about 12 g of plastic. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

A headband in a soft wave, 157 mm across and printed in PETG the way its designer publishes it - PETG bends where PLA would snap, and a headband is a part that gets flexed every time it is worn.

A headband with a horn and two ears, 205 mm across and 6 mm thick, so it sits flat on the head and prints in one piece on the plate with nothing to glue. The band is a loop rather than a rigid arc, so it grips a child's head and an adult's. Designed by Jakub Lattenberg and printed under Creative Commons Attribution 4.0 (CC BY 4.0).
