Cooling fan and support frame for OctoPrint rig 3.5 PiTFT
thingiverse
I really liked this design https://www.thingiverse.com/thing:1601055 . Once I started using it, I found the support was not very stable. I added the Navbar Temperature Plugin to OctoPrint, and found the temperature inside the Raspberry Pi enclosure was running around 50 degrees C. I really did not want to start over making a new enclosure. So I drafted these parts to stabilize the enclosure and add a 40 mm fan to it. Now my Raspberry Pie temperature is running 15 degrees cooler around 35 degrees C. The OctoPrint Raspberry Pi Rig 3.5" PiTFT Touch Display is very stable now. It is a very nice stand-a-lone unit, and is a very handy addition to the system. I also mounted the 40 mm fan to draw air out of the enclosure. The fan mounting hardware is M3 x 20 Button Head Cap Screw.
