iDryer Unit MCU + iHeater combo for Prusa MK4S: filament always dry and ready, printer chamber holds the right temperature. 15% savings, both are DIY kits.
Two DIY bundles in one order: iDryer Unit MCU — a filament dryer, iHeater Kit — active chamber heating. Together they cover the main reasons for defects when printing engineering plastics — and cost 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.
iDryer Unit — modular DIY filament drying and storage system for 3D printers. One housing for 1 or 2 spools, up to four independent chambers in one system — each with its own temperature and mode. SHT31 sensor monitors humidity, damper opens automatically, heating is controlled smoothly without spikes.
iHeater Kit is a DIY bundle for active heating of a closed 3D printer chamber. Helps maintain stable temperature when printing ABS, ASA, PA, PC — without warping and layer separation. Works with Klipper, Bambu Lab, autonomous firmware and web portal.
iDryer Unit stops drying by sensor, not by timer. Spool is always ready to print.
Nylon and PC can be fed to the printer through a tube without removing the spool — humidity doesn't reabsorb.
iHeater keeps warm air inside the printer enclosure — parts don't lift and don't warp.
Both devices work with Klipper, autonomous firmware or web portal — choose what's convenient.
Add the bundle to your cart right now and get professional print quality without extra effort.
