It doesn't look like it should roll but it do.

This is an easy-to-print toy that only requires 19 grams of filament. It's not the easiest to get rolling but after a bit of practice, the toy will continue to roll on its own! My personal best is 5 flips.

Print Settings:

1. If using an bedslinger printer (where the bed moves side to side like the A1 and the A1 Mini), please print with a brim. Otherwise, you can print without a brim
2. Ensure your bed is clean! Wash with soapy water and dry prior to printing.
3. Print without supports
4. 0.20mm Layer Height
5. Print 50% infill with Cubic pattern
6. No Supports
