I digitally sculpted this thumb using cinema 4D. My own thumb was my reference. 

I worked with creative director Khari Streeter to create this piece. The thumb was 3D printed and gold plated, and was presented to DJ Khaled on New Years Eve for Planet Fitness. It was called the "Be Free Award."

The thumb 3D printing. It took 58 hours for the thumb, and 32 hours for the base
