I have two quick questions as I plan to print this for a robotics project I have to do in school. I need help from either @phenoptix or anyone else who has the answers. My first question is how thick of a piece of plexiglass should I laser cut this on? My second question is will this robot go below 90 degrees, below level with which it rotates? My third question is at fully extended in up and down position how tall does it come out to be? Thank you for anyone who can answer!
