This is a holder for up to 5 glasses/sunglasses. The 3MF design has been split into 2 pieces (using Bambu Slicer cut with 2 added snaps) so they can be printed with no supports. They printed fine, but I would change a setting when printing the base. The curved areas on the base might come out better with adaptive layering. Also the snaps where not too tight so I added a few drops of CA glue (Krazy glue) when assembling the 2 parts.

I have included an STL file of the full assembly (uncut). If you want to recut it and/or change the snaps, you should cut the model at exactly 7 inches (177.8 mm).
