It's been a little while since I updated the thread, but I've not been idle.
Firstly, I've built a Weaver boxcar kit, and have begun weathering it. This side of the car is pretty much done. I still need to do the other side, car ends, roof, underframe, and trucks. Plenty to be getting on with then! 
I've also built and set up the 3D printer kit I bought, and have tried a test print of an O scale EMD SW1500 switcher cab. Over the next few weeks I'll be trying to get other parts of the loco printed out. It's pretty messy at the moment as I'm still learning how the printer works, but I see it pretty much the same as you would a resin kit - plenty of flash to be filed smooth!
