ROFI is made of 22 different parts. Several of these appear more than once in the robot for a total of 35 parts. These were all designed to be 3D printed and can be made on a hobby grade 3d printer in about 24 hours. The 3D printer needs to have a build volume of at least 4.5"x 4.5"x 3.0". The first ROFI was made on a Makerbot Thing-O-Matic out of ABS plastic.
