4 -to- 1 PTFE Module

🚀 PROTOSPYRE's 4 -to- 1 PTFE Module

🌟 INTRODUCTION ~ ~ ~

FYI

Due to each users printing setup there is absolutely zero guarantees this model will work/operate for everyone the same - For Optimal Results; Please ensure filament used for this model is dried! We highly encourage using PLA PRO! - We listen to everyone's feedback and respond with full compassion. Most negative feedback is due to lack of feeding smooth & stoppages - We remind you to please ensure the feeding holes are absolutely clear and unobstructed prior to assembly & use. We encourage everyone to also test the device using filament changes on a small test model so you can listen and see if any resistance is shown within the module.

This Module is a part of the Rev 1.x series, indicating its enhanced features and improvements over numerous other versions that relate to this structure. The 4-to-1 functionality of this module makes it a valuable addition to ANY printer, providing adaptability and efficiency.

*Different Mountable options coming soon - Final Mount Options (Completed) Finalizing Release - Updated 03/26/2025

Due to the recent H2 series release, were gathering additional specs but as we currently see it - This adapter is FULLY COMPATIBLE
