The minis are the Wizard's 28mm. I feel like the crates are too small for "Legion Scale", it will be easy to scale them up, wanted to make sure I wasn't crazy in my scaling.

1:48 scale is a 1/4" = 1 foot and as long as you can see over you can shoot, and as long as the base is hidden it's cover.

The height is fine but it would have to be wider, not shure you can fit 3 minis behind it. Very cool though

This looks good. I do agree the pieces might have to be wider to fit more miniatures behind them.

We can always just buy more sets of these if we need to on the website: imperialterrain.com

You only show 2 pieces here but you show 3 pieces in the picture on your site.

The two printed are the initial test pieces.

The three pieces make up the STL file. Today I scaled the sizes up and re-positioned them better and re-printed.

I will be adding additional variants as well so that there will be 2x of the new "small size" 2.5 in by 2.5 in and 2 inches tall, the attached picture shows the new scale.

Correct me if I'm wrong but both the commander and 2 other units have to be behind terrain to receive the benefits?

Honestly, I like the original size for the Legion figures. The smaller containers look like something that can be carried by the legion sized figures. The only issue is there should be more of the containers, rather than an increase in size.
