Customized version of https://www.thingiverse.com/thing:1571860

Created with Customizer! https://www.thingiverse.com/apps/customizer/run?thing_id=1571860

I edited the customized file in tinkercad to add the attachment guide. I also added cutouts for air intake. No supports are needed. The nozzle opening is 35mm

Then I wanted a larger attachment. The customizer wasn't good for making a large item with a 30 degree slant so I ended up designing my own in tinkercad.
