Cameo tool holder for Ikea Skadis board

I have a Silhouette Cameo 3 and Cameo 4. With all my tools, it's hard to remember what I have in stock and don't. I plan to label and date my tools so I remember when it's time for things to go.
The back three rows are 16mm diameter and the front row is 15mm. The Cameo 4 tools will only fit in the 16mm.
The Skadis board from Ikea is far better than a regular peg board.
