About this 3D model

Added switch cutouts for the switch I purchased from AliExpress , added two pass through holes for wires, and made a cutout in the back to have space for wiring. I should have purchased a 3-positition switch, but used 2 switches to allow for turning on all the time, or using a thermo-switch (35 C). Here's the tinkercad I used if you'd like to edit for your application: https://www.tinkercad.com/things/icNQh55cqvr/edit I'd make the cutout deeper (used 3.5 mm, could be 4.5-5 mm) and slightly wider pass throughs (used 5, could be 6 mm). Enjoy
