Base for use with small clamp

use the cup or glass holder from www.thingiverse.com/thing:764907, and use a 4" clamp (Part # 68974 from Harbor Freight) to be able to securely clamp your glasses to any horizontal surface up to about 4" thick.

If you found this useful, please thank the designer of the original wineglass and cup holder. it was his idea, I just changed it for my needs.

(Remember, if you want to print two holders for stemware, you can't just copy it, you have to 'flip' or 'mirror' it.. Ask how I know...)
Thanks, Enjoy!
