Wall Control DDD 3x6 center peice 12 hole leather working tool holder

This is a 3x6 Center piece intended for use with Wall Control (https://www.wallcontrol.com/) metal pegboards and the DDD Printable Wall Control System (https://github.com/aderusha/DDD-Printable-Wall-Control-System).

in the DDD System this is a 3x6 Centerpiece.

It has 12 holes for hand tools. The upper hole is 14mm diameter and the lower hole is 7mm so the tools should stay upright.

My specific use case is leather working tools.
