3D Printed Gastropod

I have posted about this 3D model before but I printed it again this time with grey plastic. It reminds me more of the rock color of Loxoplocus fossils found in northern Kentucky Ordovician limestone.

Here are several images of a Turritella shell printed on a 3D printer. The design was created in modeling software. Link here: http://www.thingiverse.com/thing:13668

It was printed with grey PLA filament from 3D Solutech: https://www.amazon.com/3D-Solutech-1-75mm-Printer-Filament/dp/B00ME88QPC/ref=sr_1_3?ie=UTF8&qid=1486541162&sr=8-3&keywords=solutech+3d+grey+filament
