This is a multipurpose mount designed for the BigTreeTech EBB SB2209 USB 1.0. 

The EBB SB2209 USB comes with a small USB to CAN adapter. I was not able to find any suitable mounts for this small chip and thought I would try my hand at making one for my Enderwire Build. It came out great, and I wanted to share it with others. Realizing that there would be many using this board, with more using them for non-underwire builds than others, I redesigned it to fit on a standard voron spec DIN clip for electronics. It can also be used as a stand alone item using the screw holes, or with 3M VHB tape holding it in the electronics bay. 

The board mounting holes are sized to fix a voron-spec m3 heat insert.
