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.

A can cap that opens the can as well: press it over the top of a standard 355 ml tab can and the drink is covered between sips, with the opener moulded into the same part. It prints in one piece in about forty minutes with no supports.

A lid that presses onto an open drinks can and slides shut, keeping dust, wasps and debris out of a beer or a soda between sips. Two fits are on offer: the standard can, whose lid measures 1.4 by 1.9 inches, and a wider one at 1.5 by 2.4 inches for a fatter 16 oz rim. Each prints as a lid and its sliding cover, and the standard lid also comes in the designer's looser-fitting version for a can that runs tight. Designed by Tiger prints, who remixed EcoDad's Printables lid - both makers are credited on this page - and printed under Creative Commons Attribution-ShareAlike 4.0 (CC BY-SA 4.0).

A pinecone geocache: a hollow cone with a screw-on cap and a loop at the top for a string or a length of wire, so it can hang in a branch. It prints in two pieces and neither needs supports. For a cache that lives outdoors, PETG keeps its shape in a hot car or a sunny hedge better than PLA. Designed by Soalar, who remixed it from Izak02's Pine cone cache - both makers are credited on this page. Printed under Creative Commons Attribution 4.0 (CC BY 4.0).

A T-rex that holds your page: the dinosaur stands on the spine of the book with its legs either side, and the tail curls over the top. It prints flat in one piece, 3.6" tall. Shown as a render, not a photo.

A guide that keeps a garden hose off the flowers: the hose runs through the roller and the stake holds it where you want it, so dragging it round a corner stops flattening the bed. 4.7" tall, printed as a body and a stake. Shown as a render, not a photo.

A bee feeder for the garden: a shallow dish with a landing grid so bees can drink without drowning in it. Fill it with sugar water and hang it or set it among the flowers. The picture is a render of the printable model, not a photograph of a finished print.

A kicking tee for rugby: a 120 mm base with a stem that stands the ball at the angle a kicker wants, so a conversion or a kick-off starts from the same place every time. 110 mm deep and 72 mm tall, printed as one piece with a wide foot that will not skate on wet grass.

A golf tee with a ball sitting on its cup, printed as one piece - a desk trophy, a party favour or a cake pick as much as a tee. 2.3" tall, and barely a gram 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 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 mosquito trap that uses a jar you already have: a funnel that drops into a mason jar's mouth, so a jar of water and a spoon of sugar becomes a trap. The cone lets a mosquito in and the jar's own walls keep it there. Three funnels come off the plate, 76 mm across and 47 mm tall, for the jar sizes the designer covered - standard jam jars among them. Designed by IanFoulds, a remix of the Mosquito Trap by Urasxman, and printed under Creative Commons Attribution 4.0 (CC BY 4.0). Shown as a render of the printable model, not a photograph.

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.
