Cup Holder For Walker

My grandparents needed cup holders for their walkers, so I modified a cup holder I had printed off for my desk to be able to mount onto the walkers. 

The original model can be found here: https://www.thingiverse.com/thing:4537000

Printed in PLA and used M3 bolts and inserts for the clamping section.

No supports needed.

I printed it on my Bambu Lab P1P and it took about 2.5 hours.

Edit 1: Added a 90 degree bracket.
