Luke (Whittlesticks) Heaton hit me up a week ago and asked if I'd thought to design one of these. I hadn't, so I did.
I've been printing these out of PLA, using gyroid or tri-hexagonal infill set at 50%. I want them to be light but still withstand a hammer blow when fretting. I also find using a raft for adhesion produces the best results and makes it a lot easier to remove the supports you'll need to generate for the magnet hole in the bottom of the base.
