This is a thing I created for Easter to have a nice box where I could put chocolates for my daughters.
In order to keep the egg in place during all the printing process, rafts are required. No supports where required when printing the egg at 100% size. If printing a bigger model, then supports might be required.
No supports or rafts are required for the lid.
In order to fit the lid in the egg, a small adjustment might be required in the opening below the egg using a cutter. At first the lid is tight but after use it is easier to close and open this 'box'.
This is my first 'public' design. I used OpenSCAD to create the egg and then I used MeshLab (and a tutorial) to add this 'Voronoi look'.
