This is a remix v5 of the case designed by freshwaterfish1, with a voronoi pattern set into the back of the case. The dimensions of the case have not changed, so it will be a snug fit like his original design.

I designed this for print with MJF or SLS, I'm not sure how this will come out in FDM with the narrow channels. If you are attempting in FDM maybe try VoronoiCase.stl instead of VoronoiCase_R2.stl, it has a flat bottom and may adhere better to the bed.
