Elegoo Mars 3 heating module

This is my modification for heating module for Elegoo Mars 3, original design is by Martian Wong.
The parts and wiring are the same, I used 12V 50W PTC heater insted of 100W.
If you use 12V heater, all parts and adapter should be 12V. Same for 24V.

UPDATE: I designed and added wall in front of the heating element, because of the bad printing lines during printing. The heaters current causes those bad printing lines, this addon eliminates this. You can glue or fix with screw to the main body. Printed with Esun PETG.

PLA red color with 20% infill.
