Centauri Carbon Complete Exhaust System

I printed the wall penetration section out of ASA, and the rest of the system from matte black PETG. Each piece has a socket for a male or female end, and I fused the parts together using Weld-On #3. Just apply a little on each part, hold them together for about 30 seconds, and they'll stay. I give it an hour or so before handling the glued pieces, and 24 hours to fully cure. The wall penetration pipe is printed in two parts that must be glued together before installation into the wall. The inline duct fan is a 4" variable speed fan that I found on Amazon. It's quiet and works well. The fan and the elbow to manifold connection are friction fit and NOT glued. The gasket is TPU and is optional. I found no real difference between using it and not using it, but I like having the option. You can cut the pipes to length with a pipe cutter, or use your slicer to cut them to fit. The duct pipe and elbows are all 50mm, so using a 2" hole saw for the exterior wall worked perfectly. I put silicone on the molded collar, pushed it flush with the siding, then slipped the removable collar on from the inside and fused it in place with the Weld-On. I designed a shelf for the duct fan to sit on, and it's strapped down with 4" hose clamps. I ended up needing to space the shelf out from the wall about 25mm, so I made some quick spacers to fit behind it if you need them also. I scuffed each joint a bit with 320 grit sandpaper before fusing.
