WS9290 Mammoth Muffler Conversion

This is still a WIP, CAD will be released when it's more complete. 
Bom is also a WIP, you'll basically need everything from the original, and a 
34mmOD, 31mm ID, 1.5mm H gasket
 use 1mm foam tape to seal around the fan exhaust and the filter's intake 

Included are mounts for the usual 3mm back panel, and another for use with the monolith panels. 

this works specifically with the WS9290, however if I get the chance, I'll make versions that fit the wm9290 and other models with similar form factors. 

heavily modified to fit a ws9290
