This is a holder for a 3 piece deburring tool set. I saw several models that would hold one tool with it's replacement bits, but I also wanted to have storage for the two chamfer/countersink tools that my kit came with.  The larger holes are 19.3mm and the smaller holes for the replacement tips are 3.7mm. It mounts onto a Multiboard tile using pegboard clicks.  I printed it out of ASA, but it should work fine in other materials as well.

This is the exact deburring tool set that I designed this for, but there are many generic brands re-selling the exact same tools: [https://www.amazon.com/gp/product/B08SLBT6SJ](https://www.amazon.com/gp/product/B08SLBT6SJ)
