This is a quick design created purely for myself. I purchased a chair from office works that has arms that raise and lower. Unfortunately the little noggin broke and the arm couldn't stay lifted.

I had to pry the metal rod out of the original version that had broken, it will be a friction fit and shouldn't require glue.

this is a quick 16 minute print on a bambu, I printed in petg. There are two models, one with slightly fatter noggins that I'm about to test (the original seat thing-union) but the noggins are too small.

go ham with this one on remixes and use it to help fix the chair if you have one!
