I like the design of LINDBERG n.o.w. glasses but they're very sensitive and crack a lot. I managed to use my manufacture guarantee 2 times (got me absolutely free new glasses twice!) but they broke for the 3d time! So i got some carbonfibre plastic, mashined it to fit perfectly and bolted it to the cracked location!https://ift.tt/2nV3kiv via /r/DIY https://ift.tt/2PsLT5s
