Cooling Controller for Enclosure

thingiverse

I'm planning to add some enclosure cooling since it gets too warm in there, which can't be good for the electronics, and PLA prints are failing due to heat creep. I have a spare power supply and an 80mm fan, so I drew up this design. It needs a W3230 temperature controller, but you can buy one from eBay or Banggood for loose change pretty much. The case fits the T-360-12 power supply, and clamps fit 1x1.75mm wire. I'm thinking of printing a flexy seal to fit under it, but it seems to work okay right now. There's no wiring diagram, but you should be able to figure it out if you're looking at this. My enclosure has inlet vents with check valves, designed by someone here, and you'll need an inlet if you're using this design. The temp controller requires M3 brass threaded inserts, 80mm fan, 8 x 6x2 magnets for optional HEPA/charcoal filter box, some connector block, and some screws to mount. If printing this power supply case, you'll need mounting screws, a power switch, and some wires etc. The temp probe just passes through a pre-drilled hole in the enclosure, and I designed a mount to get it into a representative area of the enclosure for measurement. The filter box is a remix with magnets added, but I can't find the original right now to give credit. I added the instructions for the controller since they were a nightmare to find.
