4-Egger - Magnetic Egg Holder

Updated version of the modular, Magnetic, Customizable Egg Cartons. Changes below:
- Added some material between eggs to strengthen build.
- Widened pieces holding magnets so less corners are sharp on the final build and the overall design is stronger.
- Added some protrusions for ease when gripping to open the holder.

*Depending on orientation, holes may fit perfectly or be slightly oversized. This was designed for 6mm x 3mm magnets to be superglued in each hole so slight oversizing of holes is not an issue.
*Sizing of pieces made to snuggly fit the average large Chicken egg (egglands best was the sample), oriented with the wider part toward the cap.
