This is not my design, I am reuploading it for preservation purposes as I can lo longer find it anywhere. That being said:
I would recommend printing with a skirt because there isn't much bed adhesion, supports are mandatory, I use 0.12mm resolution because that's the minimum my printer can do, fell free to change to 0.1 or whatever your printer supports. 20% infill works fine.
