Ervocom Referee Paging System RPS2156 battery cover and End Cap

These Things replace breakable/loss-prone parts of the Ervocom Referee Paging System.

I will be awaiting word during the 2019 season as to how the parts hold up.

I chose ABS plastic not so much for its physical characteristics but because it's the filament I had in black.

The original battery cap includes a spring which helps to make the cap less likely to twist off. I plan to substitute some adhesive-backed foam on the inside of the cap.
