This is my design for self leveling / gyro cup or a MUG holder. You can install on adult walking aid, baby stroller handlebars for bicycles.
I was inspired from the design https://www.myminifactory.com/object/3d-print-self-aligning-cup-bottle-holder-24003
I create it for MUG with handle and for coffee CUP.
To connect the rings I used a M4 x 18mm screws.
