Two spirals in one print: an outer shell that twists one way and a core that twists the other, turning past each other as you fiddle. Printed in a single colour it reads as one tapering cone; give the shell and the core a colour each and the two spirals separate in the eye as they turn, which is what the designer's own pictures show. The profile that prints it is 0.2 mm layers, 3 walls, 15 per cent gyroid infill, PLA, no supports, standing upright exactly as supplied.

Design by NerdHerder

Design by BeninManc

An inner cone passes right through an outer one and neither of them comes apart - that is the whole trick, and it prints as a single piece. Roll it in your hands and the two bodies slide past each other, which is the part that keeps fingers busy. Printed in two colours the cones separate in the eye and the pass-through reads as impossible; printed in one it looks like a solid cone until it moves. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by What3d

Design by dominator334

A fidget spinner small enough to live in a pocket: one piece, no bearings, no axle to glue, printed in place so the two halves and their weights come off the plate ready to spin. It is a 15-minute print in the designer's own profile, which is why it makes a good giveaway or market-stock item. Printed in a silk filament the spinning face catches the light. The picture is a render of the printable model - real photographs of the print go up once the first one is made.
