Cooling fan and support frame for OctoPrint rig 3.5 PiTFT

thingiverse

I really loved this design at https://www.thingiverse.com/thing:1601055 as soon as I started using it, but I quickly discovered that the support wasn't very stable. After installing the Navbar Temperature Plugin on OctoPrint, I found out that the temperature inside the Raspberry Pi enclosure was running a scorching 50 degrees C. I definitely didn't want to start over from scratch by making a new enclosure. So, I designed these parts to stabilize the enclosure and add a 40 mm fan to it. Now my Raspberry Pie temperature is running a much more comfortable 35 degrees C, a whopping 15 degrees cooler. The OctoPrint Raspberry Pi Rig with its 3.5" PiTFT Touch Display is now very stable. It's become an incredibly nice standalone unit and a super handy addition to the system. I also attached the 40 mm fan to draw air out of the enclosure. The fan mounting hardware I used is M3 x 20 Button Head Cap Screw.
