There are pieces I'd like to get, like "door rail" inside and outside corner plates, double-sided plates, 1x1 and corner masonry bricks, 1x1 panels (not a corner, more like Lego 4865), as well as pieces that aren't made in the color palette I want.
I've looked at Lepin and I see that they do have some increased color palette options for "door rail" pieces, as well as masonry bricks, but I'd like to go further (they only have 1x2 bricks/plates for each of those options) without resorting to pay $12+ a piece for items on shapeways (that would get very expensive very fast). Even $2-3 a piece wouldn't be so bad if I could just get what I want in the colors I want.
Is DIY 3D printing currently the only real option here?
