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’m afraid not. I’ve never magnetised a model before, you could probably manage it with the turret gun, but the sponson and hull weapons might be a bit small to fit the magnet.
