This should fit any of the wera micro tools with shanks ≤ 60mm. Although the design can be easily modified for longer shank tools.

It is based on Gridfinity and it is stackable so you can keep all your different bits separate but within arms reach, all within a 4x3 footprint. You can color code or even add some text to the sides to designate what is contained within each tray. 

Gridifinty m3 floating holes removed for better prints with no supports

Feel free to modify as you see fit. 

I recommend printing with ≥ 10% infill, no support, 0.4 nozzle, 0.20 layer height or less, 2-3 walls, PLA or PETG
