Designed in ProE, to be printed in PET-G for its ductility and low shrinkage. created in order to recycle my broken Aviators as I like the thin lenses, will fit 0.8mm thick lenses as is. ideally to be super glued to lenses but do grip quite well without. Bridge piece grooves are inset in order to accomodate different shaped lenses, scale to fit your face/lenses. best printed as in images with lense grooves vertical, mirror arm in slicer to get right and left arm.
Pictured was printed in around 3hrs total @ 25mm/s on stock CR-10 in PET-G with 0.15mm layer height out of a 0.4mm 260degree nozzle, from multiple concentric walls instead of infil for durability (long extrusion of horizontal profile) , steps sanded down after a few hours hardened
