I apologize ,can u explain where the strength issue is? maybe I can fix it? Is it maybe the 2% infill? I haven't had any issues with the ones printed as of yet. let me know Thank you

si in pratica la parte nera non ha legato bene con la parte rossa, forse bisogna aumentare la percentuale di sovrapposizione delle due dopo il primo layer..

ok I think I see the issue. What size did u scale it to? that way I can try and reprint it that size and I can upload new version with better settings for smaller size? I noticed when I rescale it to a smaller size, I needed to lower my layer height to something finer.
