Filament Feeder with Attached Filter

This is a filament feeder, with a magnetic attached filter. It will feed the filament through your enclosure and filter any dust or particles from it.

The magnets hold the filter securely in place, but allow a quick filament change.

The design goals were:

• Easy to attach and remove after each spool change.
• On top of the enclosure.
• Minimal additional pressure on the filament.
• Working with the existing 16mm feed-through hole.

Print instructions

All parts are best printed using PETG with a layer height of 0.15mm. The feed-through parts (101 and 102) are obviously printed with the disc on the print bed.

The filter shells (2 × 103) are printed with the flat side to the print bed. You need to insert a pause command, just before the holes for the magnets are covered.

Best, you make a test print to check the correct hole sizes for your magnets. They need to be inserted with some friction, otherwise, they will snap out of the holes if the print head moves over them!
