About this 3D model

Summary hi, created a Puzzle Cylinder whre the maze is on the inside of the outer part. So its not visible until solved. Looks like there are some small problems with the overhangs (i just started 3d modeling). I printed some in PLA, ABS - all worked fine. So it can be printed and used. If you want to help me improving the thing just write in the comments. Jens Print Settings Printer Brand: Creality Printer: Ender 3 Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0,1 mm
