Really Useful Box Miniatures Tray

Tray for Really Useful 9L box for minuature storage in two layers. Saw something similar for legions imperialis and designed this one larger miniatures. 70mm high and with two on top of each other they are clamped in place when the lid is closed. Enough space in a 9L box for 4 trays. I've added magnetic sheeting so the miniatures stay in place.

No need for supports and printed at draft layer height for speed.

Edit:
These trays are designed for the 9L boxes you can get in the UK, for US use the following scaling method, provided by user dlog13:
