Round Welding Goggles

thingiverse

Goggles designed to fit 50mm lenses from the welding supply store. If you plan to use them for welding, they might work for gas work but definitely not for electric welding processes. Make sure you know what you're doing. The lens area isn't deep enough for both a shade lens and a protective clear lens. I printed on a resin printer. I doubt the threads will work on a FDM printer. You may have to scale the thread ring in the x-y direction to get the threads to work. It'll depend on exposure, materials, etc. Scaling in the Z direction will throw the pitch off and will definitely not work. I put in a small setback on the eye piece so you can print threads down without a problem if there is a small elephant foot on your first layer. Similarly if you print flower side down, an elephant foot will not be a problem. I printed with supports on race where the lens contacts the eye piece. I'm not sure these were necessary. Use 1/4" for the nose piece and 1/2" elastic for the strap. The bumper will need to be printed in a flexible material so it can stretch to fit. You could also probably just slit some silicone or vinyl hose down the middle.Materials: Elegoo ABS-like and 3DMaterials SuperflexNote: This is a V1, The angle of the lenses on Eye_Piece doesn't quite work for me. I suspect it might work for some though. For me the V2 eye piece works better. The bumper doesn't fit quite as well on V2 though.
