3D-printed products and 3MF downloads from Roxium in Burlington, Ontario

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 low-poly heart, faceted like cut stone: the low-poly build keeps it light and lets it catch the light along the facets, and it stands on its own on a shelf. 3.4" wide, printed in one piece. Shown as a render, not a photo.

A tall vase with a drop falling through its wall, and the tray that holds it: the designer made it for a single stem or a bundle of dried grass, and the tray catches whatever you drop in it, which is where the mindfulness comes in. Printed as two pieces - the vase and its holder - so you can use them together as an arrangement or keep the tray on a desk for rings, keys and incense. Standing 24 cm, it wants a shelf with headroom or the middle of a table. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

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 DAD heart gyro fidget: a heart with DAD cut through it, mounted so it spins in the frame when you flick it. 1.8" by 2.2", printed in one piece with the pin already in place. Shown as a render, not a photo.

Design by LangHjornArt

Five heart shapes, each layered front to back so the colours read as depth: black sits at the back as the outline and the two layers in front are yours to choose, so one colour is the simplest and three makes it pop. Pick the shape you want - each is about 1.6" by 1.5", with a loop for a keyring or a chain. Shown as a render, not a photo.

Design by Print3DFamilyFidgets

An elephant charm in flat relief, trunk curled, with a hole at the top for a keyring or a chain. Shown as a render, not a photo.

Design by dominator334

Design by LangHjornArt

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

Ten layered fidget discs off one plate - each about 3" across, each with its own cut-through pattern and its own way of spinning and clicking. Pick the design you want; the picture on each chip is that disc. Shown as a render, not a photo.

Design by PenguinPrototypes

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.

Design by eclien

A ball that screws into its own cage - the thread holds it, and it spins from one end to the other without ever coming free. 3.9" tall, printed in place in two pieces that come off the plate already assembled. Shown as a render, not a photo.

Design by Elaak

A beer crate for batteries, scaled down to sit on a shelf: stacked sides, a slotted top and a handle you can actually lift it by. Holds a row of AA or AAA cells - pick which, they are separate crates. About 2.7" long. Shown as a render, not a photo.

Design by JSBallpython

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.

Design by PenguinPrototypes

A frog that jumps: press its back and it springs off the table, and the pond bowl catches it. Pick the frog on its own or the bowl with it - the bowl is 5" across, and three frogs fit on one plate if you want a set. Shown as a render, not a photo.
