Skirmish Movement Tray 25mm base

My first attempt at creating anything for my 3d printer. This is a simple Saga movement tray for four miniatures in a skirmish format. I am quite happy with my first attempt.

Improvements that would be nice to achieve in a update:
- chamfer the top edge
- make multiple bases fit exactly into each other. Not sure how I will be able to achieve that.

I made this in Tinkercad
