Prusa Mini Filament Guide + Filter Attachment for Sensor Holder

Prusa Mini Filament Guide + Filter Attachment for Sensor Holder

This attachment can hold a ~16mm x ~16mm x ~10 mm foam cube to filter dust / hair / foreign debris from your filament to help prevent nozzle clogs.

This design features a customizable filament guide that is inserted into the top of the attachment. I've included 3 variants:

1. 4mm PTFE Tube Clamp: This will securely hold a standard 4mm PTFE tube.
2. 6mm PTFE Tube Clamp: This will securely hold a standard 6mm PTFE tube.
3. 6mm Solid Guide: This provides a simple 6mm guide for bare filament (no PTFE tube required).

This design simply attaches to the "Prusa Mini filament sensor holder" base piece without any modification.

This attachment is compatible with the original base from "Prusa Mini filament sensor holder" by Štěpík (https://www.prusaprinters.org/prints/24951) and is also compatible with my improved base remix, "Prusa Mini Filament Sensor Holder - Improved Base" by blaker9410 (https://www.prusaprinters.org/prints/32801-prusa-mini-filament-sensor-holder-improved-base).

I'm happy to share this with you and I hope you find it useful! This design took me many hours, 4 major iterations and countless minor iterations. Please considering donating if you found this useful! I'm happy to improve and tweak the design based on your feedback - let me know!
