Velleman MK138 Thermostat box

Had a go with Tinkercad trying to make my first thing and this is what i came up with, needed some scaling in Cura but managed to make it work :) if it is not quite right in any way then the files are saved at tinkercad's web site.

I plan to use this along side a mains voltage thermostat that uses a heat light to heat a printer enclosure, when the temperature gets to warm the heat lamp shuts off, this mk138 then turns on an exhaust fan and also a 12v strip light to replace the light from the heat light.

Instructions

I used Tinkercad, never tried designing anything before so this is my first.
