Giá giữ mũi vít nam châm 4 & 6mm cho Wall Control System

Wanted to use these bit holders on my wall with the Wall Control System slots. Shaved barely 1mm off the bit holder top and bottoms so they fit flush with the left and right side pieces from the DDD Wall Control System parts from Luma. Remixed those side pieces to have 5mm holes where I can pushed in some M3 brass inserts. The I just screw on the 3 bit holders using M3 screws. 

The rectangular holes in the side pieces are part of the original DDD wall system. It means you can connect this to another DDD part that you want to put right next to this one using the DDD pegs. 

Other Parts Needed: 

1. 6 brass inserts sized M3x8x5 (8 inserts for 4 stack)
2. 6 M3x8mm screws (8 screws for 4 stack)
3. 15 magnets sized 3x3mm per row. (45 for 3 stack. 60 for 4 stack)

Update: Added 4 stack version so there won't be a gap between two sets of the 3 stack version. The main image shows a 4 stack above a 3 stack. Two 3 stack versions will have a gap between.
