Enclosure heater

thingiverse

This is an enclosure heater for a 3d printer. Takes 3.5mm screws in the bottom, slide in a 120mm fan and a ptc heater like this: https://tinyurl.com/ycyjk8yw. use a generic relay based temperature controller with an external relay, or any other little heating controller you want. Note: This can happily burn your house down and shock you with live voltage. be careful. Parts list: 1 shroud 1 floor bracket 4 3.5 mm or smaller screws to attach it to whatever you need 4 m3 screws to attach the heater, they just screw into the plastic so don't go too tight. 1 120mm fan with a power supply of some sort 1 heating controller Method: slide the fan into the floor bracket, route cables outside. Screw heater onto shroud. slide shroud on top of floor bracket, glue if you want or mod it with screws, or just leave it as a friction fit. Wire up temperature controller and power for the fan. I recommend using a smart power strip, so it turns on the heater when your 3d printer starts drawing power. could also maybe rig up your printers mainboard or use octoprint or something, not experienced in that so I don't know.
