H2D External Spool Holder

H2D TPU Spool Holder – Designed for Smooth Flexible Filament FeedingThis custom spool holder is designed specifically to hold TPU filament spools and guide the filament cleanly into the H2D system. The geometry ensures that flexible filament travels straight into the PTFE tube with minimal resistance, improving printing reliability when working with TPU or other soft materials.The holder also allows you to attach the original H2D swivel filament guide, ensuring full compatibility with the stock system.Although my prototype was printed in PLA, I strongly recommend printing the holder in PETG or another heat-resistant material. This is not because of extruder temperatures, but because the overall printer chamber/ambient temperature may cause PLA to warp over time.FeaturesMade for TPU spoolsThe holder is designed to reliably support TPU filament rolls and maintain a stable feeding angle.Compatible with the original H2D swivel guideYou can directly mount the original filament guide head wi
