I have had a pair of frog become too loose because the orbital nub has become too worn down to secure the legs. I thought about many different ways to repair this and none seemed like they would do the trick. I just recently had a thought that I wanted to run by you gents. I think if you could remove the orbital nub from the damaged pair and remove one from an undamaged pair and swap the nub. I think glue would hold it but I also thought of somewhat melting the plastic some too. Does anyone have any thoughts about this? If your moda3 were not wearable would you do this? It would not be a visible repair when displaying or wearing the shades.
