Here on this Thingiverse page you will find yourself a very customizable trapped sphere. Use Customizer or download the SCAD file to customize the cube size, hole sizes, and sphere size.

Please comment if you have any questions or comments, post a make if you make one (or more), and/or remix if you use Customizer. :)

I would recommend you print with a raft or supports 'touching buildplate' to support the base of the sphere.

Be careful when removing the raft. You may need to clean the base of the sphere a little.

I used OpenSCAD to create this thing.

• Customizable height to make tall cages
• Adding pictures

2018/05/15: Added rounded edges.
2017/11/18: Fixed scaling problem.
2017/11/16: Published thing.

BTW, if you change the sphere size smaller than the cube size, it would be floating in the middle, im working on dropping the sphere down to the ground if you make it smaller.
