I've been designing some models for 3D printing. Some of my models can be found at
https://compactwargaming.blogspot.com. I also have Napoleonic, 18th Century, Ancient, and Viking Dark Age ranges in the works. They're all similar style. The goal is to have something that is easy to 3D print, paint, and get to a gaming table. I was inspired by the simplicity of games like One Hour Wargames and The Portable Wargame. I've successfully printed and painted models down to 18mm scale, but a well-dialed-in FDM printer could easily handle 15mm or smaller. A resin printer would probably handle 6mm or smaller. 15mm and smaller is beyond my painting ability so I haven't tried that.
My question is do you think they'd be good for getting younger players into the hobby? I can imagine a parent printing up a set to play with their 10+ year old or a 20 something getting into the hobby via an existing 3D printing hobby. If I sell the files, where would you go to look for them and what would you expect to pay? I know there's some things out on Thingiverse, but for every printable model, there's several duds. Would you prefer to buy an entire range (i.e. 18th century of several nations), nation specific armies of a range (i.e. British AWI) or purchase individual models. I have modeled the units with intersecting individuals so that they print easier, are more drop resistant, and require less painting. For everything pre-black powder, I think its an appropriate approximation of close order formations. Should I continue to offer units pre-assembled and merged or as individuals?
