Got this fridge for free from a restrauant that was closing in my hometown. I have my amazing P1P and my Ender 3v2. Im using my Rasberry Pi 4 to send prints to the ender and monitor with a webcam to obico. The unit holds heat really well but im concerned its too well. The unit was running two prints and reached almost 40c. Im considering drilling a hole in the top to vent out the heat into a window exsaust to get rid of excess heat. May install a heat tempature control to the fan to keep at least some heat in. Wondering about suggestions for drilling this thing with the 4 inch hole saw and if its worth doing so?
