Snapmaker J1 cabin extension

This is a 70mm extension for the snapmaker J1 for a bowden clearance and with integrated 50mm fans 12V for cabin temp controlled by a Temp/PWM circuit board.
The STL file of the front panel is without my logo ;-)
Use 15mm diameter washers (M4 or M5) for the corner bottom and 15mm diameter x 3mm neodym magnets for the corners upper - then u can use the original lid without any additional fixings
