Gridfinity Universal Tool Holder Holder

This is a Gridfinity storage solution for a printable universal tool holder (https://www.printables.com/model/279459-universal-tool-holder). Bins can stack ontop of this, and bins on top will freely slide without catching on the contents.A 10-collet and 12-collet version have been designed. The 10-collet version is accidentally a bit provocative.
