Camp chair drink holder (foldable)

My camp chair has hard arm rests and didn't come with a drink holder. So I've created one that folds up when not in use.

Camp chair is a Boab brand.

Prints in place and depending on your printer tolerance and accuracy, you may require some very slight sanding to allow the upper arm to click into place. You may also require some support to the upper inside part of the opening, however this will depend on your printer and the  filament used.
