Hello, I recently came across a Shapeways product that really helps my MP-03 Masterpiece figures do the one thing they have always had trouble with: stand up. So I was looking on Shapeways and came across these and they really help. I have two MP-03 figs, Starscream and Skywarp (obviously), and ordered one pair while Shapeways had their recent free shipping to see if a set would work. And they do really well! (i'm not getting a kickback, this is all me) They fit in very well, not too tight, and once I paint them should look even better. Anyway, I figured I would post this in case any other MP-03ers out there might be interested. They're listed as "MP Jet Dude heel extension", they come in white for $7.52 and black for $9.52 and they're made by The Veef Shop.
