I've just finished tweaking this Leman Russ proxy, inspired by the very original model released for Epic back in the 80s. It's designed to be easy to print in FDM (no supports required for printing), the one pictured was printed on a stock Ender 3.
I'm fairly happy with how this one turned out, I've a little bit of tidying up to do, but hope to have the model up on Cults3D next week.
I have a fairly bizarre workflow due to my background in 3D modelling (I wouldn't recommend this to anyone). I did the early concept work in an old copy of Sketch-up pro (for speed), finished it off in blender and then re-scaled the models in Cura (because it's less of a faff than doing it in blender).
