This simple elbow fits in the exhaust port of the DVC580 cordless vacuum to redirect air flow up instead of horizontally into work area. I often find myself blowing the dust around that i'm trying to pick up.
Simple friction fit. There is a channel for locking but didn't seem necessary; extra printing complications and strength of “nubs” probably not sufficient.
This is my first design (just learning CAD) so it's a simple design.
The author marked this model as their own original creation.
