@@OliverLaskoski thanks, yeah I made them all a few years back on a program called rino. Really advanced learning curb and kinda spendy but I was in a class for it. Recently, there's been a few times I needed some extra units so I've been using tinkerCAD, it's free and really easy to learn, you can only work with basic shapes but I've been able to make some nice looking models with it. It helps that A&A units are at such a small scale to hide any mistakes
