Cup Holder for T-Slot or anything you want to screw it to.

Cup Holder for series 15 extruded aluminium (You can screw it into anything you want though. 2x4 piece of lumber. A tree near your tree stand.) How I Put it all together: Order the 15 Series Roll-in Panel Mount Bracket from 80/20. My design skills aren't good enough to design my own. Here is the link. I chose the regular as it was cheaper: https://8020.net/panelsdoorcomponents/panelmeshmounts/mountingbrackets/rollinpanelmountbracket/15-series.html Screw that mount onto a 1.5" x 1.5" piece of wood. Screw the Printed cup holder onto the side of the wood. Roll the cupholder into the T-slot. I made this extra Large to fit hug mugs. It also works great for Tulip Beer Glasses and anything else. I know it's a niche piece, but I had a need, I designed it for myself, and thought I'd finally give back to everyone. Use it however you want.
