Sega brace filament guide and filter

A guide and filter to work with Bowden setups...

I used a cheap magic eraser sponge for the filter just cut to size and push the filament through the eraser and holes.
Add a extra piece on the outside if u want like in the last photo..

I used a regular sponge before and cotton swabs but the magic sponge catches the most dirt its very porous I cut a lot of wood and have dog so I need good filter
