Two Trees Sapphire Pro drivers fan duct
thingiverse
Drivers fan duct for Two Trees Sapphire Pro printer + MKS Robin Nano V1.2 control board. Two cutouts were added for the FAN connector and for TMC2208 UART connectors. Compatible with the TMC2208/9, might provide the best cooling even for 5 drivers in a row. Tested with 2 TMC2208 boards. The duct mounts right on the fan, you can tighten it with screws if you want but it fits tightly even without it. Walls fit perfectly between driver boards and connectors on both sides. 05.11 update: cable clip mount added on aside. 06.11 update: all air blown surfaces are now smooth.
