This is a Bit holder for Multiboard. It has a multipoint rail socket and it needs  ONE of this multipoint inserts:

• Flush Big Thread - Multipoint: 4 pcs: [https://thangs.com/designer/Multiboard/3d-model/Flush%2520Big%2520Thread%2520-%2520Multipoint-1123331](https://thangs.com/designer/Multiboard/3d-model/Flush%2520Big%2520Thread%2520-%2520Multipoint-1123331)

   

  OR

• Big Thread - Multipoint: 4 pcs:  [https://thangs.com/designer/Multiboard/3d-model/Big%2520Thread%2520-%2520Multipoint-1123317](https://thangs.com/designer/Multiboard/3d-model/Big%2520Thread%2520-%2520Multipoint-1123317)

Print without supports, in orientation provided in .3mf file. Default PLA settings and you can use 2 colored filament if you wish.

Holes are a little loose as hex bits come in different sizes, tolerances, and I found out that some of them are too tight  as they are bigger. 

There are profiles, corresponding to 2 sizes of hex holes. Print the LOOSE one and only if you are brave, print the TIGHT ONE. 

If you have any idea of how I can improve this design, please feel free to make a comment.
