Bought a 2nd set of the Jinbao OS KO Predaking to display in individual bot modes, and designed replacement heads for Leodux, Bovis, and Fortis (aka Razorclaw, Tantrum, and Headstrong) in order to get rid of their comically oversized stock heads. Available now through my Shapeways shop.
Thanks so much for the purchase! I really appreciate it. =) Depending on how the Shapeways tolerances turn out, there may be some very light, gradual sanding required for the ball joint hole on the head (just at the opening of the hole). Lightly sand around the opening, try to press the head on, repeat gradually if needed. My home test fits needed a tiny bit of sanding, then snapped in place for a nice firm fit.
Mine just turned up earlier than expected. Very impressed! It's a shame these guys need so much work, but it's getting there...
If you buy it through Shapeways, it is default printed in yellow, so you'd only need to add a little bit of red for the visor and orange for the face mask.
I could, but I'd need reference images to see what the general preference for their look should be. PM me and we can try to arrange something.
