Parts 72490c01, 72490a, & 72490b

[Matthew]

Hello, I was just trying to build a Lego Blimp/Zeppelin for Lego Ideas in Stud.io, but sadly none of the parts for the actual envelope of the blimp/zeppelin seem to exist.  I did get the gondola completed as I intended, but sadly without the actual balloon, (or envelope as it's know to those who know airships), I can't make the upload.  I tried asking the folks at Bricklink to help with making the envelope, but sadly they couldn't seem to find a 3d model of said balloon.  So, anybody here think they can help with that?  Please?  It'd be really appreciated if somebody here could, especially if you could make all three parts, the blimp container assembly (72490c01), the blimp container body (72490a), and the blimp container tail (72490b) both with and without their stickers, (especially since I plan on using a plain blimp container body with the tail fin stickers on the blimp container tail on my Lego Ideas project, so having the two ends separate and the complete assembly with and without stickers would be very helpful).  So, yeah, just thought I'd ask.  Rockatoa, Brickticks out!
