Since the existing inserts for castle combo did not fit for my sleeved cards I designed my own one. 

It ist a very simple insert that work with thick sleeves.

Theoretically, the shorter tray only needs to be printed once, as the other one remains empty, but I printed it twice so that the components cannot fly around.I would recommendend to do so. Maybe this empty tray can be used for a small pencil etc. 

The lid closes completely
