Reuleaux Triangle Fidget

A satisfying pocket fidget based on the Reuleaux triangle — a curved geometric shape that spins and rocks in a uniquely satisfying way inside its square frame.

Print in place. No assembly. No supports.

Just slice and print — the triangle rotates freely inside the frame straight off the bed.

Print details:

•  ~30 min print time
•  13g of filament
•  Any FDM printer (fits on the A1 Mini)

Perfect for desk fidgeting, a quick gift, or just showing off what print-in-place can do. A great beginner print that always impresses.
