Mask to Cardboard Joiner

This is a two-part threaded spacer that can join a thin plastic mask to a piece of cardboard. All you need to do is drill a 6mm hole in both, and screw the two 3D printed parts together to join them. OpenSCAD source included so you can size the length to match the parts you are joining if they differ.

Printing Instructions: Use 99 perimeters, so it is solid and strong. I used PETG, but PLA should work as well.
