This model fits a tissue box with max size: 230mm x 115mm x 70mm (LxWxH)
If you want to use other parts from existing vw bus models scale them to 165%!
This is a rather big model and a big bed is needed (300mm x 300mm)
For smaller print beds use the models with "part_1" and “part_2” at the end.
For the assembly please check the image.
You only need some glue, nothing else (maybe a tissue box ;) )
