Not exactly deep-sky stuff, but it is my other main hobby.  This is a 3D printed 5th order Menger Sponge, 180mm along an edge, printed on an Anet A6 3D printer using Rigid.Ink white PLA filament.  346 hours of printing and 1.5kg of filament went into making this mathematical object.

Got today’s EPOD (number 97 for me) with an image of Romanesco Broccoli showing its Fractal structure.

Thank you Jim at EPOD for continuing to publish my work.
