I made this cup holder for a LEVO Rolling Laptop Workstation Stand.   

A step file is included so the mount or cup area can be modified as you desire.

The mount is for a 36mm sqauare with large radii to fit the LEVO middle riser.

Cup area is 80mm diameter x 65mm deep   3mm thick walls.

This is for insulated drink holders.  They are called “Bubba cups"  in Texas.

Made out of PLA, 0.3mm steps. 20% infil, 4 passes for profiles.   

4 M3 x 25mm screws

4 M3 thin square nuts.  About 1.7mm thick nuts.
