Sunglass side shield for snow

prusaprinters

I made these for hiking in the mountains with my regular sunglasses. Of course there are specialized glasses for this for the professionals, but I rarely need them so I made my own. I have included the FreeCAD model. You can replace the photos of my glasses with your own, and adjust the sketches as needed, although knowledge of FreeCAD is necessary. I have no idea how to make this parametric, other than the size of the vent holes on the side shields. Otherwise this is an example of something that worked that you can use as inspiration.The 3mf file includes support blockers in PrusaSlicer, so that only the ear piece clip is supported. No other supports are needed, and if added they are hard to clean up. I printed them in black PETG.
