Here is what I call my drill bit forest !
This is a plate for holding my set of 0.1mm stepped drill bits. (I purchased the set without any case).
The build is quite obvious for the wooden part.
The top glued paper sheet was drawed with my CAD software, printed on good paper, glued with white wood glue, and then varnished.
If someone needs the drawing, feel free to ask, I have to dig into my hard drive, but I certainly still have it.
