This is a rod and drink holder in the same packet! Rod can be adjusted and locked in place. I used a m8x40 bolt and a nut to lock the rod in place.

Print settings:

I used PETG but i think ABS and PLA will work too.

For the bracket i used 100% infill and others 30% infill.

0.2mm layer height

I recommend using support.

For the installation you need:

screws for the bracket
m8x40 bolt
m8 nut
