Base for Workable Doors

This is a base for RobagoN's amazing Working Doors (https://www.thingiverse.com/thing:2929682), set up for Gloomhaven. It took me a long time to get my printer dialed in to print the bridge on the doors, and in the meantime I ended up with a bunch of working "single" doors that needed some way to get joined together.

While playing, one of my players mentioned that he actually liked those ones, since he didn't have to worry about bumping the archway when putting his figure on that space. S
