70mm to 100mm Vent Adapter for the…

Ender Plus 3D Printer Enclosure with Exhaust Fan Interface 

Vent inside help support the outside adapter and secures to each other. I found the tent was sagging slightly and causing stress without support. 

I used M5 x 15mm phillips head with lock nuts to attach because I had those spare to use. Holes will also use M4 with washers. 

Printed with 3 walls and 3 x for top/bottom. Infill is whatever, I used 20%.

So far it is working much better than before. ABS/ASA were still leaking smell into the room previously, now I can't smell the ASA. 100mm inline fan is pulling it out the window.
