This is a cute accessory for the table top game Wingspan. It is meant to hold the eggs which are used in the game.
This model is a remix of a model from Thingiverse by “njeff” which has a lot of horrible overhangs which make it unfriendly for FDM printing.
I have used Blender to remove the nasty overhangs, spindly strands, and holes in the base. I used Microsoft 3D builder to repair the model. It is easily printable now, demonstrated by the pictured print resulting from my Prusa i3 MK3S+ using eSun PLA+ filament.
The original model is not on Printables, so it is not listed as a “remix”. The original model is at:
