Next up was a gear-driven scissor lift. I prototyped with Acrylic and Delrin.
Turns out that the material properties of the Delrin aren’t ideal for laser cutting. There was a little meltiness and a lot of unevenness along the cuts. This created a lot of friction and twisting along the vertical axis when the lift was constructed. I even added springs to assist with closing but the friction was too high for them to make any difference.
