Since I have a printer with a small build volume (Flashforge Dreamer) I was not able to print the GASB One.
So I decided to split the files and glue them together.
I also uploaded the OpenSCAD file if anybody has a smaller printer as the dreamer is.
To use this file, please use the original file of Carletto73. Only the file GASB1_V7c_rear_repaired.stl is uploaded by me, because Carletto73's file is broken and unable to be opened from OpenSCAD.
