Full details are available at http://2manytoyz.com/engel-thermostat.html. The Engel fridge is ideal for camping, traveling, or when the grid goes down. The issue with this fridge is that it came with a dial, featuring settings of 1 to 5. This thermostat operates on a temperature Delta, which means if the ambient temp changes, so does the inside of the fridge. To address this problem, I built a digital thermostat that's external and requires no modifications to the fridge itself. The goal was to create a remix of this case large enough to fit all components. The following products were used in the build and testing: Engel AC/DC Portable Tri-Voltage Fridge/Freezer with ABS Plastic Shell - 40 Qt: https://amzn.to/2G4Gn6M Creality CR-10S 3D Printer: https://amzn.to/2UloHaJ Hatchbox Gray PLA Filament: https://amzn.to/2G3cXFU Hatchbox Black PLA Filament: https://amzn.to/2CM6s7l LED Holders: https://amzn.to/2DE2qj7 Assorted LED Kit: https://amzn.to/2DBYIWZ Digital Thermostat 12V: https://amzn.to/2G4Oujq DPDT Switch: https://amzn.to/2SbM2hF Bosch Type 12V Relay With Wire Harness: https://amzn.to/2CRU45Q Inline Fuse Holder: https://amzn.to/2WhLwhr 12V Cigarette Lighter Socket: https://amzn.to/2FRB0Iz Lascar USB Temperature Data Logger: https://amzn.to/2CNRBcm As an Amazon Associate, I earn from qualifying purchases.
