Wall holder for (many) glasses

Two sizes - one for naked glasses ("low"), one higher is for glasses in case/etui


Two types - without and with ("fill")  filling the back and front parts at an angle - to make it easier to print (without small overhangs)

and:
Two types - “lowest” with additional hole, for screwing to wall at bottom, and “Middle” (which goes at top, too) with only holes at upper part, and pins on bottom to hold other module bellow. 

They are stackable, they hold each other on the pins at the back. only lowest one and topmost should be screwed to wall.

And - at last - Top Cover for hidding screws:

This top cover can be printed upside-down, due to small area of bed contact. Or printed on back.

Printing - 4 wall loops, rest - default (3 top/bottoms, 15% infill) - on bambulab printer can be printed without supports, brim etc - just as is. 
If you have ugly places in overhangs - try “fill” version, this should be better.
