After breaking Tracks' flight stand off in Ironhide's iron hide yesterday I decided to make this real simple piece to fix it. I trimmed the entire 3mm peg off and designed this to be like a cap that fits over the wider portion of the mount. Fits like a glove! I didn't have the broken peg for the length so it ended up a little long. As you can see from the layers, I printed it out sideways so the peg would be stronger. Look away if you're squeamish. Yeah, a little long, but it works. I may trim it down. Yay, he can fly again! Didn't realize I had a happy Lego head in the picture as well.
