Description

I initially tried to print this https://www.thingiverse.com/thing:3887203 but it didn't work out so I designed my own that doesn't require supports. I use the same hose that is referenced in the other build. I also added a set of adapters for the drivers side vent. The angled drivers side adapter does require supports under the outlet that hangs over the build plate. Dorman 708-083 Use ABS or PLA or other high temp material as suggested sas64.
