Kingdom Rush Character Tray

I bought a knight pledge on a kickstarter where there is no trays (only in expansion) for character so I decided to design my own.

Lid printed with honeycomb infill and 0 top and bottom layer.

EDIT #14.01.2021
I added v3 and v3-excision.
Now the box can hold 3 trays side by side. Additionally, the v3-excision version has a finger cutout for easy removal
