Voron 2.4 - CPAP /Carbon Pellet/ HEPA Filter Exhaust w/ Muffler & PG7 Mount

I wanted a rear exhaust that worked with CPAP and also had a HEPA filter + carbon pellets. This is my solution to my own problem. Please let me know if you have any troubles printing this model at all. 

I haven't tried this design out for other printers, namely Trident, or Micron. Please try this out and let me know if it works! 

[ONLY ] Muffler Remixed From: https://www.printables.com/model/831149-voron-cpap-with-muffler

As per request I've added M3 heat insert versions of the muffler and Exhaust Grill. Muffler will be using M3x35 bolts.

Updated: September 22, 2024

PG7 Mount Added to Grill and Base Plate. Please pick these items from the folder below.  Installation is the same as CPAP tube. Route cable from Exhaust Grill to the side hole where CPAP wires will be exiting on the right side of Base CPAP plate. Then route all the way down the back of the printer.  Note that PG7 is a M12x1.25mm thread so double check this before printing. 

The can cable that is spec'd to fit is this one (Roughly 5.5mm in diameter cable will work): https://biqu.equipment/products/bigtreetech-ebb-sb2209-can-v1-0?variant=40273695342690
