DIY-Filament-Dryer-v2

This repository contains the hardware designs and firmware for a homemade WiFi-connected filament dryer, which is a device that removes moisture from plastic filament spools before they are used in a 3D printer. Wet filament is a common problem for 3D printing hobbyists because moisture absorbed from the air causes print quality to drop, leading to weak parts and surface defects.

The project is a second version of an earlier design by the same creator, and it adds WiFi connectivity so you can monitor or control the dryer remotely. The repository includes both the electronic hardware files and the C++ firmware that runs on the device, so you can build your own from scratch if you have the skills and tools.

The creator has also written a documentation page that lists all the parts and equipment you would need to build it yourself. A YouTube video walks through how the hardware and firmware work together, and the README recommends watching it before diving into the files. For people who prefer not to build the electronics themselves, a pre-assembled kit of the custom electronics is available for purchase, though you would still need to source some standard off-the-shelf components on your own.

The README is brief and points mostly to external resources: the documentation site, the YouTube video, and the creator's blog post. All the actual build files live in folders within the repository, organized by hardware and firmware.
