Boden like guitar - fixed

Resized and repaired [Calgon](https://www.thingiverse.com/thing:4667569)'s obj files with netfabb and exported as STL. "bodyx06" is too large to fit on my i3 MK3S+ heatbed, so I cut it in the middle - in the slicer (original object remains scaled and repaired, but in one piece). You can use my 3mf file for that.
