Giá đỡ kính đơn giản cho 2 hoặc 3 cặp kính

Basic glasses stand that can hold up to three pairs.

There are two version: one for narrow glasses that can fold and occupy little space (as the pictures ones); the other for larger frames so that the majority of models can fit.

There's no need for supports, and the models can be printed with your desired settings. 
I printed them at 0.28mm with PLA with an Ender 3 v2.

UPDATE (26/06/23): strengthened the main column for both model files

UPDATE (28/08/23): added a new model for 2 pairs of glasses, “2b_glasses-stand_05”. This is specific for glasses with slim arms (like the ones in the pictures), I designed a larger holder and a little extrusion to give them more stability.
