Enki at #ERRF2019


Our second year for the East Coast RepRap Festival! We met tons of awesome people, demonstrated our green-pink-yellow thermachromic filament for the crowds, and showed off our new mascot, a 1 meter tall, 6 KG 'Enki of the Deep' statue, designed by Loubie3D.

Enki consists of over 30 3D printed parts, ranging from 5 minutes for the pupils to over 60 hours in print time for the rock. His tailfin, head, and horns are attached by magnets for easy transport, the voids for which are built into the model. The other parts have pegs to hold them in place, with the help of some hot glue.

The body, printed in all Capricorn PLA filaments, is hollow so wires and lights can be run inside. The rock, printed in Fillamentum Mukha, has a hidden magnetic door and room inside for a batteries and electronics. The smaller parts were printed on our Rostock MAX V3's, and the largest parts on our Tevo Little Monsters, outfitted with Captubes.
