How do you rubber band a DR4B? I know that you should make a triangle and I know that @antichamber made an online rubber band calculator tool but the tool is in 35 hole C channels when I’m using 25 holes 1 x 1 cut c channel. So do you just randomly pick places? Or is there a way to use the online rubber band calculator for this too?
PS. How do you use the calculator? I didn’t want to “revive” old threads because people seem to not like that.
