What a great project! I printed the shell and large parts in PLA and the delicate interior parts in resin. Love the transparent look in which they turned out!
Printing was straight forward. I used BChapys stackup Excel to guide through the process and this video https://www.youtube.com/watch?v=AfvY2CTTjUE to assemble.
It doesn't actually turn all that well, I think my LPT spool isn't quite perfectly symmetric. But it's a display piece anyways (and a huge one at that.)
Black, White, Blue
I used some modified parts for the fan shroud, the combustion liner and the stand.
The bearings were a really tight fit and I had to do some sanding, so make sure to dial in your printer!
