My team has two pieces of plastic that have been cut from the legal sheet size. We are planning to use it to move our ball up to our flywheel and we have a spot that the ball curves upward that we would like to zip tie to ease pressure instead of connect using a formed metal plate. Would this be legal?
Yes, teams are allowed to ziptie lexan sheets.
So long as you use zip ties from VEX or identical ones from elsewhere, that is legal. It’s not legal if you use zip ties different from the ones VEX sells. Other sorts of zip ties are only legal for wire management.
