Yep, was thinking the same. And all the other brands of fitness devices…

Glad i could help!

The planet itself will survive this easily, the inhabitants on the other hand…

Sorry I am short of time, but hopefully I can help:

Instead of using negative modifiers, just load the full part as it is. Then rotate it (Usually ±90 degrees) around the x or y axis and use the z cut tool to cut the part in half. Only keep the part you want. Reverse the initial rotation and the object is now cut on one side.

Redo the steps for all 4 sides.

Edit: also this might help (dont know, if it’s an beta option): https://help.prusa3d.com/article/cut-tool_1779
