Adjustable Circuit Board Holder Span

I purchased a PCB holder and it had a max width of 9". That was too short for a project I'm working on, so I made this modular span replacement.

The pieces are 30mm x 15mm x 120mm with an additional 10mm for the plug ends. There is only mechanical friction holding them together, so I would suggest cyanoacrylate glue or epoxy once you have the length you need.

The board I have is about 11", so I printed one male end cap, one female end cap and two spans.
