iHeater: Compact Heating Solution for 3D Printer Enclosures

## Project Summary

iHeater is a compact and affordable solution for 3D printers without an active heated chamber or with limited motherboard connectivity. It’s especially useful for printers with proprietary boards that don’t have extra ports for fans, heaters, or thermistors. iHeater solves this problem in a simple and universal way.

There are currently two versions available:

* **100W** for small and medium printers
* **200W** for larger enclosures

iHeater can operate as a **standalone device** with its own firmware or be integrated into **Klipper** as a secondary MCU over USB.

## Key Features

* Heats the printer chamber up to 60–70°C depending on the version
* Powered directly from 220V — doesn’t overload the printer’s PSU
* Works with Klipper as an independent MCU (e.g., STM32F042)
* Optional standalone firmware with physical button control
* Compact, safe, and easily integrated into any enclosure
