I just remixed losredoe132's towel holder to clip on to the side of a LACK table from IKEA for use with a 3D printer stand. It also uses 4 #8 3/4" wood screws to secure it. I also extended the hub in the middle of the locking rings a bit. I haven't printed it out yet but I will post photos when it is done.

Thanks for the STP files!

UPDATE!! I redesigned the clamp for the towel holder. I had the wrong dimension for the LACK leg.
