Space Base Boardgame Playerboard Holder

This is a playerboard holder (inspired by https://www.thingiverse.com/thing:3740227) for the boardgame Space Base. The game requires you to slide cards underneath the player boards, which can get messy. This holder attempts to prevent that.
This does support sleeved cards, but you won't be able to store them in the box (maybe one).
It has been split so that it can be accommodated by smaller printers (190x182mm max)
