Civolution - Insert with Acceptance Letter

This is an organizer for the board game Civolution:

This insert began with using some of the work from Fabmaszter:
https://www.thingiverse.com/thing:6811736
Where there are some prints to go inside of the existing boxes. I've included those files I used in this insert unaltered. I wanted to accommodate sleeved cards and a display for the research cards. Also, I wanted to be sure the whole insert worked for vertical storage. 

The 3mf file includes lettering for the research display boxes which you'll need to assign with your ams to set as different colors. The stl files have those letters cut out. There's just enough space in the upright nook to hold 5 sleeved cards when the game should only at most have 4 there (discards go to the bottoms of the decks and only new ones flip once per round). 

Everything prints with no support necessary. See PDF for layout.

Note: player technology chips stay in the boards as per the original intent of the game to make the next setup quick.

For the acceptance letter expansion, I've changed what was a spacer Katzenoma's good work here (incorporated in the print profile already). If you don't have the expansion, find the original spacer in the profile as well. Note, it goes in on the top right pictured position of the bottom of the box (above the player boards).
