Hesine M-505 (i3) Filament guide

For Hesine M-505 (i3 clone)

a Filment guide with included dust remover. just insert a piece of sponge inside the barrel and guide the filament through. can be mounted directly on a 8mm frame or even a M3 nut can be inserted in the pocket and the guide can be bolted on the frame (havent needed it so far)

this has improved the filament feeding much. Also see my spool holder in addiction to this.
