Belay Glasses

I made some belay glasses used for climbing,
No glue, no other parts, except the prisms, get some online for about 10$, e.g. here:

The sides can be printed in standard, which is small, medium and large, the only difference is the bending radius.

You should consider to print the rivets not as single part if your cooling is not very good, I recommend printing either mutliple rivets (10) or print it with the glasses alltogether.

For sources please contact me.

if you like it, donate be a beer ;)
