    I wanted to see if I could make something that works out of nothing other than PLA rather than actual, good eyewear.

    I live way up north in the boonies so it’s not like we get massive amounts of sunshine here. And there’s always the trees to provide shade. But they might come in handy every once in a while in the summer.

    They’ll let UV through but no more than 25%, since that’s the amount of light the mesh lets through. But hey, for the price, I can’t complain 🙂

    Also, I suspect the PLA will crumble very quickly if it’s hit by enough UV to damage my eyes…












  • I thought of doing something similar, but dovetailing the edge of the hole and making the plug slightly thicker so I could actually hammer it in - possibly cold - and make the material flow into the dovetail. Exactly like metal inlays. This would mechanically lock the plug in place.

    Unfortunately, the walls around the magnets are really thin, so any hammering or applying heat beyond what a printer would apply laying filament on them is likely to deform / destroy them.
