Catacombs (third edition) barrier supports

These are supports for the card barrier in the third edition of the great board-game Catacombs by Elzra.
The problem I found with the card barrier that it always wanted to swell and take space on the table. The guides firm up the barrier and keep it straight.

I have added the Fusion 360 file as well as the .stl's
