IPIN3D had a great design, but I wanted to make things a bit more "modular" and add thermostatic control.

Parts needed:

  • uxcell a12080600ux0947 Bimetal Temperature Control Switch Thermostat    https://a.co/d/bmQTtVG 
  • Conext Link STU-6R25 Un-Insulated Spade Terminal 25 Pack (#6 Stud, 22-18 Gauge)    https://a.co/d/gTQaEPs   (These fit the terminal lugs VERY nicely on the PrusaXL)
  • Expandable Through Hole Solder Adapter Board for Electronic Breadboard Modules, 8 Pins, 4 Positions Each Pin, 0.1" Spacing – 10 Pieces   https://a.co/d/6siopFy 
  • Jst XH 2 Pin Connector Kit Total 40 Pcs Jst Male and Female Connectors,20 Pcs Sockets with Total 100 Pcs 22AWG 210MM Balck Red Wire Cables Jst-xh2.54MM 2pin https://a.co/d/gPKjn1C 
  • various heatsinks if desired: https://a.co/d/6O0UqRE 

Thermostat switch will sit right in the center of the frame near the components.  I used the included silicone sleeve as the gripping device

The angled “leg” of the fan mount plate is sacrificial, it will snap right off cleanly (at least it did for me in Prusament PC-CF)

The 3MF file has the mouse ears, zero gap supports, I used HIPS as my interface material.  It worked, and took some effort to remove but worked wonderfully in terms of leaving a nice surface.
