Well after a lot of effort I've loaded a few models. I'll probably keep them available until I tire of it or it seems like there is no interest. I recommend detail materials (white detail, transparent detail, or black detail. These show grain but any other material is worse. All parts are designed optimally to be printed in detail. It also seems the detail material requires some cleaning with hot water and a brush, from the gel support material.
Fighter combat: These are generally between 25 and 40mm in length, optimized for painting (IMO) but still usable on a 1 and 1.5" grid.
Fleet combat: Capital ships are centered around 75mm while fighters are between 1 and 1.5cm (roughly). They work best on a 1.5 to 2" grid
Collectable: Certain ships, generally the ones I really like and want bigger, will be scaled up to around 150cm. But expect these to be pricey due to material required.
