I wanted a solution that I could stack the large amounts of Silly Shells I have been collecting.  

This is not meant to used for transportation of shells, just a simple desktop style solution.  

4 corners are elevated from the center and sides to provide a nesting solution that serves as pillars to stack another shelf on top.

Granted stacking will only work with the “standard” size shells, but you can still put the larger shells on the topmost deck to have them in there as well.

Printed with following settings:

Printed on Bambu A1 and Prusa Mk4S  (Also use a brim unless you have a extra grippy build plate)

(Pictured) PLA, PETG also works, whatever you have.  

Minimum 2 Walls, with 8% infill, and “Snug” support on the build plate to give the shelf some support. 

If you have filament to spare:  3-4 walls, with 15-20% infill and “Snug” support on build plate
