Hello,
I've just recently got back into buying Lego again after 20+ years, and it was the Star Wars theme that pulled me back. Needless to say, I am a true noob when it comes to making mods (and MOCs are out of the question).
Anyway, I got myself the ISD 75055 and while I really love it, it bothered me that the top portion was not solidly attached onto anything and could slide around freely (especially when swooshing). I tried searching for a solution online, but couldn't find any (maybe because it was already so obvious and therefore no one felt the need to be publish one).
So with the best of my own extremely meager abilities, here's the solution I came up with (it's basically just 2 parts placed on the surface):
With those 2 parts in place, I can now easily attach the top portion to the main ISD body and keep it from sliding around. Another benefit is that having the top part attach in this manner keeps the 2 halves of the main body perfectly aligned with the center, satisfying my OCD.
That's all! Again, I realize that this is a super simple mod and maybe it's not even worthy of having a topic. But I guess I wanted to share it anyway since a couple of the reviews I watched/read on the 75055 ISD mentioned this issue. Please do not be too harsh on me if this mod seems like a simple no-brainer...
