A buddy of mine is going to 3D print a bass body. Rather than attempting to rout (route?) out pickup cavity spots after the body has been printed, we're opting to have the cavities printed in the first place. I'm thinking I want to put humbucker pickups of some variety in it, currently looking at the Seymour-Duncan Thunderbird pickups. However, I have no idea what the dimensions for the cavity should be. This is a bit of an experiment for both my buddy and myself, so I'm not going to purchase the pickups until we get the body printed. I would assume the SD replacements would be a drop-in replacement to regular Thunderbird routes. Does anyone have any references for Gibson-style pickup cavity dimensions? Have one they might measure? Any and all information welcome. Thanks!
