UPDATE 1: I have added a little video here for you to see all the gears moving:

I have here my 3D printed guitar.

I have zero music knowledge.
My friend Steve has a band called 44 inch chest and he saw the guitar on YouTube that was 3D printed and jokingly asked me to make one just like it for him.
I said I would need a donor guitar first so one day he got one at a flea market.
Then it sat in my wardrobe for about 6 months until one day I couldn't think of what to 3D print next so I started.
In terms of parts I used the donor guitar, pulled it all apart then I photocopied it and started modeling.
I had to reduce the body by 97% to get it to fit on my cr-10 because it did say it had a 300x300x400 high but the reality was a little smaller.
I did not shrink anything else only the body.
So I used the gears from a thingiverse post that someone else had made already.
I did not shrink anything else.
Because of the 97% I had to cut away a little of the wooden handle thing because it would not slot perfectly because although it was modeled to fit I couldn't fit it on the printer bed.
List of things you need to make this guitar:
about 2 kilos of pla -1 mini servo motor which I had to open to make sure it would do full rotation( I found the answer on YouTube) -1 EL wire (1 meter)(red) with its electronic part. -1 battery holder (2xaa) for the servo -glue (clear for the EL wire) -glue to stick the main guitar pieces, the bottom lid has a groove on its top for the glue to go on so it doesnt lift the lid too much with the thickness of the glue blob -wire to add length to the componets and that tube thing that you put on the wires that shrinks when you put it under heat or cigar lighter (I dont know the name but better than using electrical tape looks so professional with it and all the soldering stays put)
I wanted to fit the servo motor battery inside the guitar, I left a space there but I couldn't at the end because I couldn't get the EL wire to work without its little box ( there is some electronic stuff in it that I couldn't get out of the box so it sits outside.
I would like to find a way to fit it inside (my electronic know how is not the best)
I did managed to solder all the connections and connect a switch (a key that turns the servo on).
I designed everything to conceal the wiring and made hidden little tunnels to run the wiring, and also made a little channel to run the EL wire through cleanly.
I don't know if my donor guitar is like other guitars so the design I have made works for this guitar but don't know if it would work on others.
Nu supports needed at all anywhere.
A nice big 3D printer would be nice but nothing stopping anyone from cutting it up in pieces.
If you do end up cutting it in pieces do not shrink anything then everything will work perfectly.
Enjoy
I know i did designing it and putting it together.
Also when putting screws i learned that if you put your soldering iron on top of the screw for a bit and hold it there, the heat transfers to the plastic making it easier to screw then when its cooled its stick super well.
One thing...the gears are not my design, i got them from here:https://www.thingiverse.com/thing:2218127
And have added them here so you can download everything you need from one place.
3D PRINTING SETTINGS
I used no supports
2 rolls of black PLA, and a bit of red for the gears.
I have one gear that is a little too tight in there, I suggest you print the gears a few times and see what colours work best.
you do not need all the gears I added BUT you might want to make a belt or something to hold the guitar.
I used cura so I used 1.75 nozzle, 30% infill for the main body.
BUT for the little gear holders I made them 70% infill as at first the little bits broke off but not when I made them stronger.
the gears were all 30% infill.
