Technical draftings needed...

[CrazyArcher]

Besides beeing a bassist, I'm an engineering student, and I wanna make a 3d model of bass as a side-project. It can be made a lot easier if I had a 2d drafting with all the sizes, because I can't measure my bass accurately (haven't got the tools), and moreover bringing the instrument to the university (where I work on it) will be too weird
If someone has a source, I would be very grateful.

If you don't find anything, you can always import a picture into CAD, scale it to the proper size using the scale length as a reference, then trace it. I've had to do this before when I was in a similar situation.
