Belay glasses climbing

thingiverse

I made belay glasses from a really cheap prisms I bought in Aliexpress. They are a bit bigger than the referents BG, it gives more view but also weight more. Use a small nail (heat if needed) and push it to the hinge. Electrical cable bent to place is used for the nose part. added shrink so it will be comfortable. Made it a little narrower then the originals. I might make a new version in the future because I have a few more prisms. enjoy :)
