I present to you the modular leather worker tool system. I have been a leather worker for 12 years and finally made a modular system for my tools that I enjoy. It comes with your choice of 2 modular trays and a choice of color, and you can also get your name/shop name carved on the top.
The organizer is made of cabinet-grade plywood (for strength) and it comes fully assembled with all the pieces screwed and glued, all it requires is for you to hang it (with an included homemade wooden French cleat system).

If you want a custom name on top please message me with the options while I figure out how to set this up, thanks.
