Ender Dragon 30cm

I've printed the smaller (combined) version of the Ender Dragon from Intentional3D, but the fittings got too loose. Basically, it would only be possible to mount it using glue. So, I decided to make a remix, improving the connections. At least for my printer, it worked well this way. I'm sharing the modified pieces. I suggest you to first print some vertebras (neck/tail) and see if the adjustment is good for your printer before wasting time printing everything. I really hope it works well for other people, as it's a lot of fun when it's assembled. My son loved playing with it, as you can see in the photos.
Probably, if printed in PLA, it will get loose with time, as PLA has this "property". Probably, in PETG it should withstand better.
PS: The parts Wing2A and Wing2B (bones of the wings?) have to be printed 2x, one natural and other mirrored. I believe any slicer has the mirror option.
There are images of the orientations I used for printing the pieces. Only small manual and localized
