Having more than one sunglasses, you need to place them somewhere safe… and all the stands I have had do stack glasses each above other. picking the bottom glasses makes the whole stand collapse. Angeled shape was my goal to design and print.
I did face significant problems colapsing the prints first, when supports could not hold the filleted shape of glasses holder, therefore flat contact ponts were necessary to keep. Now it is finaly OK.
PLA, tree supports are necessary (my choice was 20% angle and strong… Hope you will enjoy the design.
