3D printer bass

I’ve been threatening myself with building a bagged CF lap steel body but i’m just not quite there yet. I’ve got experience building R/C glider wings and a few fuselages so i’m familiar with laying mats on carved foam forms and bagging them. At this point it’s finding the time/motivation to carve a core.
i’ve been fascinated by the idea of a lightweight pedal steel since the first time i picked up a cased Emmons double 10. A whole lot of that thing could be done in CF and make it (comparatively) super light. I just wonder about the effect on it’s sound, which is where the lap steel project was conceived.
 
So after actually getting to perform with it, I like it. Maybe not my every day instrument, but a very cool project. It turns out it is made of ASA whatever that is, and the pick guard out of something that I can’t remember. Here is a pic of the builder Andrew.

I don’t think the sound would suffer, but you better make it stiff, because of the tension and torsion introduced by all the moving parts anchored to it. I think to see real weight savings you would want to replace many steel parts with a lighter metal like high grade aluminum (6061 wouldn’t cut it) or titanium (if cost were no object).

If 6061 won't cut it would a 7000 series aluminum be that much stronger?
That stuff is nasty to machine for alloy.
 
I think it could be modeled pretty accurately in Solid Works but the effort to design and write the code for a one off part doesn't seem like a great investment in time

I’ve had a really good look at several single and double necks and i’m thinking some properly shaped CF pieces would be enough to get it done. The steel player whose brain i’ve been picking seems to think so as well, but obviously at this point it’s far too early to know and given what appears to be a project that could very easily turn into a very long slog all strictly on spec. I’m staying pretty busy with a couple of other projects these days so any serious turn on a CF pedal steel may forever remain an idea.
 
So I did get some more info on the actual build itself regarding material etc.

Plenty of Peavey owners could use a battery box lid, a part that Peavey no longer stocks. Anyone aware of 3D printing of replacement lids ?
