Summary

I tried some eggs storage found on thingiverse and I decided to do my own.
I'm a newbie in fusion 360 so my design isn't perfect, but it seems to work.
It's possible to print all at once with a bid 3D printer or in only two parts, but it's using too much support material, so I have separated the print in various parts.
The two ramps are too big to fit in my 3D printer, so I designed invisible holes inside so I can print ramps in two parts each, and then I assemble them with 3 mm threated shaft, glue is optionnal.
The ramps are simply glued to the supports, I made notches to assemble correctly.
There is other designs possibles using shaft to fix ramps on supports if glue isn't reliable.
I recommand to place support blockers to avoid shaft holes to be filled with supports.
