Hollow Ball Assortment

I needed to print these for a research project and thought I'd post it here. I updated to included an assortment of .25, .5, 1, and 2 inch hollow balls. You can use it as a test for checking tolerance accuracy from your printer. Use it for hobbies or however you see fit! Wall thickness is 0.1 inch for all.

Bring the object just off the surface of build plate in your slicer otherwise you'll get a flat side on the ball and use support only on exterior.
