Bowling Ball Thumb Insert - Outer Sleeve

PLEASE READ ENTIRE DESCRIPTION!!!!This is the outer sleeve that goes with one of my other models - Bowling Ball Thumb Insert. This is the outer sleeve that can be used with that insert. Please note, I have tested printing this, but have not tested it in a bowling ball. It was made to match the outer dimensions of a jo po drilled thumb insert, but I have not tested it so I cannot confirm that it will work with a ball drilled for a jopo. Also, this will NOT work with a real Jo Po insert, it will only work with my other model. Once again, I have not tested it other than that the outer sleeve works with my insert. I have not tested it with a bowling ball. Please don't download it and then give it a bad rating because it doesn't work with your ball. If you download it, understand that there is a decent chance that it doesn't fit and you wasted 45 minutes of print time. That being said, if it doesn't fit, please let me know and I will attempt to fix. I made this as a request
