I created this model, and its variants, for the "Eyeglass Holders" contest hosted here on Printables. I had in mind a simple shape where I started from a rounded-top prism and worked from there. I've then proceed to add a channel to hold the glasses temples. Afterwhat I created three variants, for a total of four, for you to choose from :

1. Full: the shape in its original form, you can print it really easily even with a low infill percentage
2. Hole: the addition of the hole through the shape is probably my favorite variation
3. Hollow: looks identical to the original one but saves you some material
4. Wall: the most minimalist of the variants, lightest and it prints faster too (yet it can be more challenging due to limited bed surface area)

The stand is about 47*27*40mm.

Instructions

The stls should be in the proper orientation for you to slice directly.
No support required, the bridge is fairly small/easy.

You can hide the seam in the sharpest corner (back left for example).

It can be printed in 0.2mm. You could also use adaptive layer for example for an even cleaner look at the rounded top.

If you struggle to make the “wall” version stick to your build plate feel free to add a brim.
