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 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.

A shelf that hangs under a shelf: it clips over the front edge of an existing board and gives you a second tier in the gap, for mugs, spice jars or a router. 6.9" wide, printed in one piece. Shown as a render, not a photo.

A napkin holder with an open frame: a stack of serviettes sits in the base and the side wall holds them upright, so you can take one without the rest following. 6.3" long, printed in one piece. Shown as a render, not a photo.

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 record sleeve stands on a ledge under a patterned back panel, and the ledge carries NOW PLAYING across its face in relief, so the record on the shelf is announced rather than guessed at. 200 mm wide and 159 mm tall - wide enough for a 12 inch sleeve - printed in one piece with no supports under the sign.

A strip that threads onto a guitar strap and holds a stack of picks, so a fresh one is within reach in the middle of a song: 100 mm long and 25 mm wide, printed in one piece. It sits on the strap rather than in a pocket, which is where picks go to be lost. Designed by willywidget and printed under Creative Commons Attribution 4.0 (CC BY 4.0).

An LP on the wall: a back plate with a shelf the cover stands on and two brackets that hold the record upright in front of it, so the sleeve and the disc are both on show. 218 by 214 mm and 187 mm deep, printed as one piece.

A stand for a pair of drumsticks: a flat 195 mm base and a cradle post that takes them by the shaft, so they stand upright on a riser or a shelf instead of rolling off the kit. 238 mm across as printed, in two parts, with the post sitting in its seat on the base.

Two hexagonal mesh pockets angled into each other, so a pair of shoes sits heel-down without one resting on the other. 220 mm wide, 165 mm tall and 130 mm deep, printed as one piece. Remixed by ThatGuy123568 from jordi_id7's original Shoe organizer on Thingiverse. Shown as a render of the printable model, not a photograph.

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.

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

A flower-petal stencil 0.8 mm thin, for tracing or airbrushing onto paper, cake or a wall. 3.8" across, printed flat in one piece - thin enough to lie flush on the surface. Shown as a render, not a photo.

A pick holder with four feet that stands on an amp or a desk: slanted slots take plectrums by the tip so they can be pulled out one at a time, and the block is 90 mm long, 28 mm wide and 12 mm tall. The slots are cut at an angle, which is what stops a pick sliding back down into the holder. Designed by gareth7562 and printed under Creative Commons Attribution 4.0 (CC BY 4.0).

A rail that a CD jewel case stands in, ribbed along its length so the case leans back instead of sliding forward, on four short feet that keep the disc off the shelf. 149 mm wide and 30 mm tall - the width of a standard case, with a little room either side.

Four plectrum shapes, two of each, printed flat as one sheet: a teardrop, a jazz point, a wide triangle and a rounded standard, at 1.0 and 1.4 mm so a player can find the thickness they like without buying four packs. Each pick is about 34 mm long and the texture on the back of the thicker ones keeps a sweaty thumb where it belongs.

A practice mute for trombone, printed in three parts: the long tapered body that goes down into the bell, the flared cup that caps it, and the small collar that keeps the two together. 250 mm long and 193 mm across the cup, so it takes a full-size bell. The cup is what does the muting, so the horn can be played in an apartment without the neighbours learning the set list.

A capo in two printed parts: a jaw that sits across the strings and the lever that clamps it down, 92 mm wide so it spans a standard six-string fretboard. It goes on the neck above the fret and holds the strings at the new position, which is what lets one shape be played in any key.

A plate of music notes cut flat at 3 mm: single quavers, beamed pairs, a dotted note and the odd small rest, from 25 mm up to 67 mm long, so a wall, a noticeboard or the front of a piano can be dressed with them. They print lying down, which means no supports and a clean face straight off the plate. Designed by EcneNomma and printed under Creative Commons Attribution 4.0 (CC BY 4.0).

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 plectrum printed flat at half a millimetre, 27 mm tall and 24 mm across, with the designer's design across the face - the pun in the name is the whole idea. Thin picks bend more than thick ones, so this is the one for strumming rather than for shredding. Designed by marshal.meacham and printed under Creative Commons Attribution 4.0 (CC BY 4.0).

A volcano model 5.9" across and 3.1" tall, printed as one piece - a desk piece, or the model for a school project on volcanoes. Shown as a render of the printable model, not a photograph.

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.
