Interlocking tool organizer. You can use the Bambu shapes to cut your own shapes. I have included the fusion 360 file as well to cut your your shapes for your purpose. If requested I can upload other sized holes.

Uploaded size is 2.5" cube with a hole of 30.5mm which fits my VDI30 lathe tool holders for which I originally made this model for. I also plan to use with BT30 tool holders in the near future and will upload that model.
