My spouse found a pair of wall-mounted glasses frames on an online source (sadly, after I became interested in 3D printing). She needed more, but couldn’t find the same design. So I printed another pair (5 pairs of glasses per frame, instead of 6). You can see a comparison in the photos of the 4 frames – the ones bought are on top, and mine are on bottom.

I designed this item so you can change any parameter you like, but if you want each print to have more or fewer than 5 glasses, you might just want to change the “num_holders” parameter.
