This jig was implemented after some mistake that have place in harness connector size. The connector was wider than the gland nut (PG16) because of this, it was impossible to thread it through the nut. To resolve this problem I used Roland EGX-350 CNC machine and office hole puncher. The concept was to load 2 plastic nuts on the tray and punch them both in reason to save the time :) The tray manually moves forward and back by handle. All relevant parts were drawn in Dr.Engrave S/W (providing by Roland). Polycarbonate 4mm was used as a jig material.
