This is a mod to allow using CPAP cooling with the Calamity Toolhead. I already had the 3628 fan plate, so I designed the CPAP portion around that - the ducts are definitely not optimized, but they seem to work well on overhangs and bridging.

I plan to optimize the CPAP routing for space, most likely moving away from the 3628 fan plate (they're unnecessary when using CPAP and reduce your X travel), but will most likely create a separate mod for that. At the moment, this works well enough for me!

If using in an enclosure, make sure you print this out of something like ABS or ASA!

Installation You'll need to carefully bend the top CPAP ducts around the back of the toolhead if you already have the entire toolhead installed, or slip them on before you start securing the 3628 fan plate
