Dust Collector 4" to 4" nominal hose adapter

Custom hose to hose dust collection adapter for some random 4" hoses based on this drawing:

My brother wanted to drill his own set screw hole so I just printed with 15 perimeter layers.

I used PLA, I could print again in ASA if needed.

I used a 2mm inside brim just to make sure it didn't detach while printing and waste material, a deburring tool takes it right off. 

Fully WYSIWYG parameterized so you can load in FUsion 360 and double click on any measurements to change the model. Use parameter edit dialog to adjust the clearance user parameter,
