Just a simple eyepiece case I designed as a learning exercise in OpenSCAD and 3D printing as a whole, included models hold 6 eyepieces and are 60mm total height, ie: bottom + lid. I included the .scad file if you want to tweak dimensions or need more slots for eyepieces, adjust the column/row parameters.
UPDATE: Added pictures showing the Lid.
