50mm Ball in Box CNC

This is a 50mm ball in box model to help you dial in your CNC machine. 

Box: 50mm with 5mm rails

Sphere: 46mm diameter

Notes:

• Use the 50mm - ball-box-12mm-depth-for-makeracam.step  file when generating tool paths. It cuts down 12mm, which is the minimum amount to cut and have a perfect sphere when all sides are finished. Especially useful with MakeraCam which cannot machine the model as-is. 
• The sphere clamps hold the ball in place when you are machining the 6th (last) face. I 3d printed these. 
• The 50mm-clamp-protection file is a piece you can use to protect your box from getting damaged while clamping. If you make yours in plastic, it's easy to scratch with normal clamping force.
