This is a remix of ANYCUBIC MONO X HEATER by JVJV - Thingiverse

I found that there was a need for more room inside for cable management, so I have extended the compartment for the thermostat. 

Text below is copied from the original Thingiverse post:

Heating with thermostat for Anycubic Mono X

This project was strongly inspired by the x3msnake model. His 3D model for Photon S is probably better designed than mine, don't hesitate to check out his project!
Link to the x3msnake model : link.
And his Youtube video : link
PS : here is a video using his model : link

Since I don't have a metal case like on the Photon S (and not having the same thermostat), I wanted to recreate a 3D model. Here, the thermostat screen is oriented upwards for easier reading because the heater is placed on the base of the printer (using a magnet, the threaded holes of the base of the mono X are magnetized).

WARNING

• Don't print these files in PLA, I didn't try with ABS, but it should work, the resin is much more appropriate for this kind of application. The heating module has a power of 100W and could deform the PLA.
• Use cables of the right section to power the heating element. Operating at 12V, the current can reach 8.5A.

To determine the right section of cable to use, here is a table: link
Materials required :

• Thermostat 12V 10A W3230 link or link
• Power supply 12V 10A or higher link or link
• DC099 5.5x2.1mm jack connector supporting 10A link or link
• Heating element 12V 100W + Fan link
• Neodymium magnets 20x3mm (2 magnets needed) link or link
• Wire of the right section (I used 18AWG 16 cores cable, supposed to be able to support 5A, so I doubled it to 10A and everything is ok, no abnormal heating). If you have other cable sections, please refer to this link.
