Universal Stacking Egg Carton

This is my contest entry for FirstBuild's Icebox Challenge! With small refrigerators, it can be a challenge to fit everything you need into available space. Typically, the issue lies with horizontal space; there is plenty of vertical space to utilize if only you could stack your groceries! And cartons that eggs come in are far too wide to fit inside your refrigerator! However, with the Universal Stacking Egg Carton, this won't be a problem any longer! You can stack your eggs as high as desired. If you have multiple sizes of eggs, you can sort them by layer without having to re-scale the print for each size. And if you want a different layout for your egg container, you can use interlocking pieces to create pretty much whatever layout you prefer! I am familiar with the differences between and limitations of various printers. For that reason, basic 2X2 and 2X3 blocks can be printed without support and with loose or tight tolerances. These blocks also use less plastic than interlocking pieces. Interlocking pieces are the same for each version, except the size of the gap for insertion blocks ranges between 5 and 7 mm thick (if your printer has tighter tolerances, use the Tight piece; if you do not know about your printer's capabilities, print the Test Plate first). Plates are simply a set of four pieces of specified tolerance. The Test plate is one of each tolerance piece, which can be tested with each other to determine the optimum gap for your printer. The pieces should fit together tightly so they don't fall apart when used in stacks. I recommend filing protruding blocks (5 mm thick) to fit inside the gap after printing.
