Large Machine Vise with Trapezoidal Thread

I was just playing around with printable trapezoidal threads and before I realized it, I had designed a large machine vise…The vise has a clamping range of 120x120mm. It is good for circuit boards because plastic is non-conductive. Standard trapezoidal threads (30° thread angle ) or ACME threads (29° thread angle) are very difficult to print in an upright position. The overhangs are not supported by the thread geometry. Therefore my thread has a thread angle of 42°. This can be printed upright a
