This is designed to house the standard temperature controller and three rocker switches. 100% printable without any kind of repair.
Box Dimensions: 191mm x 110mm x 53mm, W x D x H.
The Lid has a 2mm interior lip to align it to the base.
The rectangle cutout for the temperature controller is 71mmx29mm. I use this controller: https://www.amazon.com/Inkbird...
The rocker switch cutouts are 21mm to account for shrinkage and rook to get the switches in without too much effort. Any standard 19mm rocker switch can be used. I used these: https://www.amazon.com/Support...
The lid screws and screws to secure the box down are #8. I used #8 x 1/2" wood screws for all 4. You can also use the metric equivalent.
I have an alternative blank box with no cutouts that can be customized. I can also customize this for any controller/switch/misc cutouts.
