Inspired by the dinosaur pool floatation device but twisted around so the bumps are on the inside, this vibrator sleeve will bring out the prehistoric animal in you. Suggest printing at .2 mm layer height or better. Uses a silver bullet type vibrator. Due to variations in printers if you find the vibrator is loose try using some electric tape to fill the gap. I would orient it with the head and loop pointing up so the necessary supports wind up on the outside of the neck.

134 mm tall, 103 mm wide, 99.5 mm deep, gap between neck and ring is 20 mm
