About this 3D model

Here is a simple mounting rig for the Duet 3 Mainboard 6HC and a Raspberry Pi 3B or 4B SBC for testing printer builds or to assist with RRF3 firmware / application development. The fan mount will fit any 40x40x10mm blower fan. Most fans should be a friction fit, but if yours is loose, then insert a zip tie through the hole below the fan to affix it to the test rig. A fan is optional, but recommended in addition to fitting heat sinks to the stepper drivers for proper cooling. STL and STEP files are included in the download for easy remixing.
