This model is a basic glasses mount that can be attached to any standard format MultiBoard. It does fit standard glasses along with my oversized aviators.

This is a remix of the original Idea made by @Sparks3D.

Print as is in the file with the bottom sitting flat on the plate. Supports are needed for the rear MultiBoard Mounts only. I used Tree Auto (Tree Hybrid) with a 25% threshold angle.

Printed on X1C using .16 mm Layer height with 15% infill. May want a little more depending on the weight of your glasses but the Multiboard mount is very tight and doesn't move when installed. No other hardware is needed. Push fit.
