Skull ring called "13", because of its triskaidecagone... Inner ring size: 29/32 in. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator 2X Rafts: Yes Supports: Yes Resolution: 0,1mm Infill: 75% Notes: Revision history:**13.x3g: Because of the tinny thickness of the ring, I give a try with 100% Infill... Near maximal inside diameter of 1 1/4", to test the resolution of the skull face...****Kids ring.stl: decreased layer thickness to 0,1mm and infill to 45%. Not flat on bed to let place to raft. Near maximal inside diameter of 1 1/4", to test the resolution of the kid face...****13-S5-S(meshmixer).stl: ring size: 15/32" (inside diameter). The smaller one of the family. To see if the resolution of the skull face will still be ok.**Got the printed part today, so here's my comments: maybe the thickness of the ring itself should be ok if printed in metal, but with a FDM printer, the size i choose (3/64") was not ideal and did not fit well with shells width (2X0,020 in)... Will keep it anyway but will give a try to a double shell... About the resolution of the face, I think it was limit and surely not to be scaled down! So futur designs will considerate letting the triskaidecagone and the face at this size or a bit bigger...**Actually, I learn OPENSCAD to deliver you a fully parametric ring with size choosen options, but there is a lot of things to be done until this day...***13-S75-L-R1MM.XXX: Inner diameter: 3/4"(S75) + 1/32"(L) = 29/32" in. Scaled up the size of the triskaidecagone flat face and make it permanent at 0,4375 in. diameter, Add a set of prismatic faces and scaled up the skull face. Infill set to 75% to help the inner and the outer of the ring stay connected. Reduce number of shells to 1. How I Designed This designed on autodesk inventor set to minimal inside diameter of 15/32 set to maximal inside diameter of 1 9/32
