iDryer Unit EXT + iHeater upgrade for Prusa MK4S: expand your drying system with a second chamber and add printer chamber heating. 15% savings; requires MCU (sold separately).
Two DIY bundles in one order: iDryer Unit EXT — a second independent drying chamber for your MCU, iHeater Kit — active chamber heating. Expand your drying system and cover heating — and it costs 15% less than buying separately.
Buying as a bundle, you save 15% compared to separate purchases.
Easy connection, compatibility with Klipper or standalone mode, built-in sensors and overheat protection.
PLA, PETG, ABS, nylon — the bundle maintains stable properties even of demanding engineering plastics.
EXT is not an "add-on". It's a second independent drying chamber that connects to your MCU with an ordinary network cable. Two plastics, two temperatures, one start. MCU controls both chambers — each in its own Drying or Storage mode.
iHeater Kit is a DIY bundle for active heating of a closed 3D printer chamber. Maintains stable temperature when printing ABS, ASA, PA, PC — without warping and layer separation. Works with Klipper, Bambu Lab, autonomous firmware and web portal.
EXT connects to MCU with a patch cable. Different temperatures in each chamber simultaneously.
SHT31 sensor in each chamber stops drying when ready — not by timer.
iHeater keeps warm air inside the printer enclosure — parts don't warp and don't lift.
Both devices work with Klipper, autonomous firmware or web portal portal.idryer.org.
Add the bundle to your cart right now and get professional print quality without extra effort.
