Summary This is an egg holder that fits Whirlpool refrigerator "large" door shelf (part number W10527271 or WPW10527271). It holds 24 eggs, plus few pockets for small stuff in the remaining spaces. This print is too large for my Prusa I3 Mk2 (and most printers out there) so it comes in two parts, I just joined them with superglue after printing. Print Settings Printer Brand: Prusa Printer: Prusa Mk2 Rafts: No Supports: No Resolution: 0.15mm or 0.2mm Infill: 30% honeycomb Notes: Increase the number of shells to 4 or 5 so you don't get any infill in the concentric circles, it just slows the print down (you still want infill in the flat shelf itself)
