(Remix) B28 single

As stated in the original it is not meant for 3D printing.

Issues I ran into printing on my resin printer with the original files:
The rocket wings/guides are so thin that they flake off when touched.
The wheels on the cart broke into pieces because they are hollow.
I can't print this in full at the size i wanted. The part already has some separate parts but they are flat faced and so lining the parts up or getting them centered will be harder.

Things I modified on the model:
The rocket wings/guides are thicker about 0.5 mm.
The cart wheels are now solid. They do not spin or rotate though.
The cart supports for the B28 are now centered left to right.
I can't print this in full at the size I wanted so I made some extrusion/holes for combining the main part of the rocket and the bottom easily.
