Have you ever wanted a simple and easy-to-make chamber heater for your 3d printer? Have you experienced unsolvable warping with abs-like materials? This project solves this by allowing you to make a chamber heater for a p1s / x1c that can also be adapted for any other printer. The model is specially designed so the build plate can reach the bottom of the printer in case you have a larger print. The fan also magnetizes in place with small 5x10x2mm bar magnets, making installation and maintenance easier. To clean the dust off of the fan, all you have to do is pull the fam mount off the base and click it back into place.

Warning, this device uses a very hot heating element to warm the chamber to temperatures that can cause skin burns. As with anything hot, handle it with care.

Printing Instructions

Print at whatever layer height you want out of a heat-resistant material like abs. Add a brim or raft and then add a layer pause near the end of the print to allow for a M3 nut to be dropped in. Make sure to turn supports on ( tree or snug ) and add a support blocker to the upper portion of the fan mount where the nuts sit. Happy printing :)

Assembly

After printing, remove the supports and brim then glue 10 magnets in place ( note the polarity of them ). I used JB-Weld and roughed up the magnets because superglue didn't stick very well to them for some reason. Next, screw the fan in place with 2 m3 screws around 12mm and use some kind of double sided tape to adhere the base to the bottom of the printer. ( note, there is a L-shaped slot which fits over an L-shaped ridge on the printer ) Next, connect the fan to an external temperature controller. I made a hole in the side of my printer for convenience, but in theory, it should be possible to feed the wires through the back of the machine too. Next feed the thermistor into the chamber and fasten it where most of your prints lie ( height wise ). ( My prints aren't usually tall so I put my thermistor right on the frame near the top. Also, I made a little clip for it that sticks with double sided tape. It isn't posted because there are a lot of shapes and sizes of thermistors. ) Placing a piece of cardboard between the wall of the printer and the hot air stream is optional, but it reduces thermal losses through the thin printer wall.
