iHeater - Heating Solution for 3D Printer

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 printers200W for larger enclosuresiHeater can operate as a **standalone device** with its own firmware or be integrated into **Klipper** as a secondary MCU over USB. Key FeaturesHeats the printer chamber up to 60–70°C depending on the versionPowered directly from 220V — doesn’t overload the printer’s PSUWorks with Klipper as an independent MCU (e.g., STM32F042)Optional standalone firmware with physical button controlCompact, safe, and easily integrated into any enclosure Use CasesWith KlipperiHeater runs as a standalone MCU managed by Klipper. It controls the heater and fan independently, o
