I've managed to convince Roe to create a Patreon page for all his models so those with 3D printers at home would be able to print their own models. He will gradually upload models as his time permits.
We have also made a test model/print for thinned down (correct to scale) gun barrels both for main and secondary battery. I have done a test print of it, so he would offer in the future both barrel versions for the bigger ships: one can decide which one is preferred.
