Furnace Player Tray

There's just too much empty space in that box, and I had to do something with it.

As the pic shows, you can sort your resources, upgrade chits, bid coins, player card, identifying marker, and first player marker all in one place.

Print four of these, then cut the bottom of the factory insert so it sits on top of these while still flush with the top of the box. You're removing 15.5 mm, which I did by measuring, marking, then cutting with scissors. It may have been better, though, to duct tape a razor blade right to the top of one these prints, then just drag it all around the circumference of the insert. Whatever works for you.

In the photo, I have the resources placed in three of the deep trays from https://www.thingiverse.com/thing:5014034 and the coins sorted in the tray from https://www.thingiverse.com/thing:5139569
