First of all thank you for this great design! I printed the guitar in 8 pieces and welded them together so the gaps are no more visible on the top. The backside is also welded together for stability but I let it a "trash look". Also there is an M8 rod in the 2 middle parts from beginning of the neck to the bridge. I don´t play guitar and it was a present to my brothers birthday, he was very impressed about the sound. The pickups and pots are similar to a Gibson Les Paul. The "chestburster knobs" I found fit perfectly to the model.
I also weathered it a little bit with a dry brush and silver paint.
