A gyro fidget spinner: three curved rings interlock around a centre post and whirl as one, so it prints in a single piece with no bearings and no assembly - just flick it and go. The rings are loose in their track out of the printer, which is the part that takes a few tries to get right and the reason this one gets measured before it ships.

A hard hat that goes on a keyring - the dome, the brim and the little ridge down the middle, printed in one piece with a hole through the top. 1.5" across, and it works as a key tag or a desk charm.

A phone stand with a woodgrain surface that all but disappears behind the phone, so what you see is the screen standing on the desk rather than the stand holding it. A deep groove with a lipped front edge takes a phone upright for video calls or on its side for standBy and night-clock mode, and it fits anything from a small handset up to a Pro Max. Printed in PLA at 0.2 mm layers, 15% infill, no supports. It is designed for a wood-fill filament, which gives it the grain it is named for, though any matte colour prints just as well. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

A thin blade for digging the lint out of a phone's charging port, with a hook at one end and a flat scraper at the other. 34 mm long and a fraction of a gram, so it prints three at a time in a minute - one for the desk, one for the car, one to lose. Shown as a render, not a photo.

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 flat key tag that holds the key by its bow rather than its ring, so it lies flat in a pocket and does not rattle. 2.2" long, about 1 g of plastic, printed in one piece. Shown as a render, not a photo.

Design by Katejot2017

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.

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.

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 hook keeper that clips onto the rod handle and gives a lure somewhere to sit between casts, instead of swinging at the line. Three sizes, for rod handles of three diameters; the designer prints his in PETG and that is what the shop prints here, since this is a part that goes to the water.

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.

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.

Two bands that print as one piece: the finned outer ring's ridge sits in the inner band's groove, so it is locked on but free to spin, with no bearings and nothing to assemble. The groove is a BALL RACE - a circular channel, with the ridge as the same circle held 0.4 mm off it - so the surfaces the two parts face each other across are vertical, which is what lets it print in place and still turn. The ring is 27 mm across and stands 7 mm, and the fins are trapezoids: wide where they join the sleeve, narrow at the tip, so nothing on it is a blade waiting to be knocked. It comes in three sizes, 16.5 mm (US 6), 18.2 mm (US 8) and 19.8 mm (US 10) across the finger hole, all at the same price, and the download is a 3MF with a plate for each, so you can print whichever fits - or all three. Print it with a brim and z-hop switched on: a small ring has a small footprint, and z-hop keeps a moving nozzle clear of what is already printed. The STL on its own is the smallest of the three. The photo is a render of the printable model - real photos of the print go up once the first batch comes off the printer.

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.

A pocket divot tool with a ball marker that sits in the handle: the fork lifts the green back into shape, the marker pops out to mark your line. 2.7" long, printed as two pieces. Shown as a render, not a photo.

Design by bitclicker

A ruler that folds: nineteen 160 mm segments that hinge end to end, plus the two end caps, so it measures a room and then folds down to a pocket. The full set is 19 segments; the smaller option is the same design at 70 per cent, which is the one for a desk drawer. Shown as a render, not a photo.

A hook remover with a forked end for backing a hook out and a flat end for pushing it through - the tool that means you do not put your fingers near the point. 4.8" long, printed flat in one piece. Shown as a render, not a photo.

Design by eclien

A small hook that sticks to a desk or a shelf edge with tape or a screw, for keys, headphones or a cable. 2.6" wide, printed in one piece with a flat back that sits flush. Shown as a render, not a photo.

Design by schiko

A little hand that clips onto the page and points at the exact line you stopped on - so a bookmark marks where you are, not just which page. 2.8" long, printed flat with the fingers already free. Shown as a render, not a photo.

Design by helder.bernardo

A bookmark shaped like an alligator, with the jaw clipping over the page and the body lying in the gutter - so it marks the page and the line at once. 3.9" long, printed as a body and a jaw. Shown as a render, not a photo.

Design by 3dprinting

A bookmark of a book with a coffee cup resting on the stack - flat, 3.7" tall, and thin enough that it does not mark the pages. Printed in one piece in about a minute. Shown as a render, not a photo.

Design by giessener

A flat floral bookmark: one thin spray of three openwork blossoms and leaves that lies between the pages and reads against the paper, marking the page without thickening the book. 5.9 x 4.4" overall and 1.6 mm thin, printed flat in one piece in a few minutes. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

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.
