Simple lift design, lift arm length adjustable so is the height. However no mechanisms were made to keep at desired setting except tight print tolerance which keeps the lifts secure. I plan to add bottom supports even though lifts in real life have either overhead or floor supports not both. There are much more complex lifts to print out there but I wanted to make quicker lifts as I needed many of them. I will be updating this as necessary so comment obvious flaws. If you find pins to be hard to put in, print/buy a watch band installer/remover.
