I designed an air dryer with a Peltier module to keep my coreXY printer filaments dry while printing

This is a detailed presentation of the design of an air drier using a Peltier condenser. Attached to my printers filament box it keeps my filament dry while they are mounted on the printer. I mentioned Stefan's video ‪@CNCKitchen‬ related to the effects of humidity on filaments :    • WHY you NEED TO DRY your FILAMENTS!   As well as Brett Beauregard's Arduino PID library : https://github.com/br3ttb/Arduino-PID... You will also find all the files involved in the project here : https://drive.google.com/file/d/14gjB... As well as a modified version of the code with overheating protection. https://drive.google.com/file/d/1PWcb... Post publication comments : As some of you suggested, it could be a good idea to use part of the heat produced by the Peltier module to heat up the inside of the box. But it is necessary to continue to cool the module with fresh air otherwise the all assembly will heat up as well as the cold side which would be counterproductive. 00:00 Intro 01:16 Principes 04:15 Integration 09:38 Electronics 11:16 Software & features 11:43 Conclusion
