Linkable Rail for DM screen-top initiative tracker

Ran out of room on the 200mm rail,
so I initiall streched it diagonally on my bed to max 290
I ran out of room that way also... so whats a guy to do?

made a quick and dirty way for the 200mm rail to attach to another via either toothpick pegs, or 1.75 filament ( you can bend or deform it to increase friction if desired)

works pretty good, and still fits in my travel case
