There is a plain cover model if you want to customize it!
i suggest using the ALL PIECES WITH COLOR CHANGES 0.2mm layer, 2 walls, 15% infill printing profile, it should work perfectly, however i originally designed this when i owned a much slower printer and it should print well with little to no infill, if you want to try i made the FASTER VERSION 0.2mm layer, 2 walls, 15% infill profile with settings similar to the ones i used when i first printed this.
the font i used is Midnight Constellations by Shara Weber
