This is a tray to hold all the player population cubes and influence disks for the Eclipse board game. It has cutouts for all the standard cube and disk locations, as well as windows for the important labels.

It is 260x65mm and was designed to fit on the print bed of my Prusa i3 MK2 (rotated 36deg). If you have a printer with a bed smaller than 250x210mm, this part might not fit.
