The Official Prusa Hepa Filter is currently out of stock and quite expensive once i ship to Australia. This remix utilises the same base as the official mount but replaces the HEPA mount with a custom frame
This model is an inplace replacement for the official Prusa HEPA advanced Filter. By utilising the same base it uses the original Blower Fan, Original O Ring, and original screws. Below is a link to the new HEPA filter used.
This HEPA filter is significantly larger by surface area so should reduce load on the blower fan and allow longer life between replacements. I have an Prusa MK4 (Soon MK4s) and an MMU3 and this fits perfectly without touching or interfering with the printer or MMU at all.
The original Mount will require some supports as the design is the same. The new Mount will also require printing with minimal supports and the Cap printed best with an inner brim to allow the handle to retain its bevel
All Models were printed on the MK4 with 2 perimeters for Top, Bottom and Walls and 15% lightning infil and generic PLA. The uploaded gcode is only used for the Text on the Cap and if printed without MMU should not be visible.
The new mount is off center from the blower / original mount in order to lower the new filter so that it doesn't interfere with the enclosure lid.
2 Versions for M3 sized screws
The original version that I have installed have holes for 4 heatpress inserts at 4mm.
The second version I have reduced the mount holes to 3mm to allow for the M3 to self tap.
