Compact DIN rail mount for BTT TMC5160. Holds two drivers.
24V 4010 axial fans can be clipped inside of the mount. Make sure the orientation is correct (Pushing air into the heat sinks).
Use one PCB clip from VORON repository to attach the base to the DIN rail.

Threaded inserts are not needed, just use M3 screws directly.
Make sure your printer is accurate. Undersized or oversized holes will make it hard to join the parts together.
Additionally needed
No supports required, unless your printer can't do 45 degree overhangs.
