Tissue/Filter Holder (multiple designs)

3 Simple designs for a Tissue/Filter holder to clean the Filament and prevent dust etc to get into the extruder. Its designed for a Multec
Multirap, but could also work with other Printers. The Pictures show "Filter_Klammer" which just gets put around the Z-Axis and pressed down (see pictures, might be a tight so it might need a little pressure). The other designs need bolts and nuts and get screwed onto the rail, but i think the one on the pictures is the most useful, because of its simplicity.
