Wanted a tray to hold the tokens. Something that is functional during gameplay and also can fit in the free space the box has from packaging.
Ended up making a few different versions. They're all basically the same thing with slight variations.
The groves at the end were taken from Connect 4 Token / Jeton puissance 4 by Diamondemon so the pieces sit a bit still. This helps when storing the game.
Connect4_TokenBox: Two connected trays to hold all 42 pieces.
Connect4_TokenBox_single: 1 individual tray to hold 21 pieces. Print 2 of these for all tokens.

Connect4_TokenBox_slide and Connect4_TokenBox_track: Use the Gamefold Accessories by rcragun accessory holder and attachment just shrunken a bit to fit this so the two can attach and detach. Intended use is attach for storage and detach during play and cleanup. Please note, there is a bit of a stopper built in, so it will only slide one way.
