Metcal handpiece MX-RM3E repair plug

When disassembling the MX-RM3E handpiece for repair two plastic parts (see picture, yellow arrows) frequently break. These two parts can be replaced by this single piece plug. Print in ABS or PETG with solid infill. I used thin CA glue on the handpiece barrel, silicone coax cable, and rubber strain relief and it has held up well.
