A wine glass holder that i made. For all kind of wine glass, from white to red.
You can put until four glasses, the piece is 248mm long.
There is three holes for the fixation, i used some 3,5 mm x 20 mm wood screws. Strong double tape could work too.
I made it in PLA, my desing is enough strong to hold the glasses, but stronger materials will work fine also.
Cheers!
