6" (150mm) to 4" (100mm) Duct Reducer with 90° Elbow Bend - 2-in-1

This 2-in-1 duct reducer and elbow bend allows for reduction of ducting diameter from 6" (150mm) to 4" (100mm), while providing a convenient 90° right-angle bend.

I designed this part specifically for use with my resin printer enclosure, where I needed to interface my 100mm ducting system with a 150mm port in a cramped space. 

Included is a variant of the part that adds strap hooks, that can be used for hanging or strain relief.

Additionally, a push-fit insert is included for the 150mm side that may be used to add a grill (see pictures).
