0.4mm cut 5mm outside for flange. (10mm was too thick on pegasus) Flange thickness is 1mm Upper thickness is 2.3mm Details offset by 2mm thickest part should be 2mm. Thinnest 0.4mm. 6 inch cookies are too big for printer. Resize to 5 inches. ---- extrude Z 15mm Offsetcurve by 5mm (clean up overlaps, may need to subdivide long runs) Extrude down by 1mm offset curve by 5-2mm=3mm Offset other side of curve by 0.4mm (clean up) Bridge curves (clean up funky edges) Now add detail geometry but do NOT make edges flush or union will fail. Make edges flush AFTER union.
