I wanted to mount a UCAN in the FT-EMS bracket on my Toolchanger Voron. The hole spacing for the bracket I liked was too narrow and would allow mounting to a Voron DIN rail bracket. 

I widened the spacing and resized the holes for M3 fasteners compatible with the FT-EMS ecosystem. Additionally I removed the need for heat set inserts by sizing the UCAN mounting holes to a direct thread size.
