This is a remix of the 2/6 wine glass holder I found on Thingverse.

I only needed capability to hold 4 glasses, and the snap-together version I found a little too hard to give to older people :)
I scaled the original print down to 95% to get it to fit on my MK3s bed, it still easily fits all the wine glasses that I tried.
The object is printed in an upside down (wide opening down) position to get a nice smooth (or nice bumpy) top.
