ROB The Robot Hands!

I recently found a Nintendo ROB The Robot for a good price on eBay. Unfortunately, he only came with one of the Gyromite Claws. I searched everywhere on the internet and found a few people selling 3D printed replacement claws, but no STL files to print myself. So, I decided to take the time to replicate them myself!

After a few days of work, here are the results! They're not perfect one-to-one replicas of the originals, but they are pretty close. I also made two versions of the hands used to play the other ROB NES game, Stack-Up (Thingiverse User Archonik has the blocks and platforms available if you need those: https://www.thingiverse.com/thing:2399494 )

Gyromite Hands:

Claw 1/Claw 2 are designed to be press-fit into the Gyromite Hand Base. Be sure to put a couple dabs of super glue inside the Hand Base before you put the parts together! This will ensure they don't come apart during use. You may also need to lightly sand the bottom edges of Claw 1/Claw 2 to get it to fit into the Hand Base.

Stack-Up Hands:

You will need to find some Adhesive-Backed Foam Strips to apply to the surface of each Stack-Up Hand. Black is the traditional color, and the piece should be trimmed to 1.21 x 0.38 inches (1-7/32 x 3/8 inches). Try to find foam with a thickness of 0.25 inches (1/4 inches). When trimmed properly, 1/4 inch tall M-D Sponge Window Seal works great! Two versions of the Stack-Up Hand are included for you to choose from, one with a guide indent and one without.

How I Designed This

Using an Empire 6 Inch Pocket Ruler and Pittsburgh 6 Inch Composite Digital Calipers, I took measurements from an original Gyromite Claw (pictured). I then input those measurements into SolidWorks and created a digital model of the claw. From there I converted the model files into STL files and printed them. Once they were printed, I tested them on ROB to see how they fit and adjusted accordingly. Overall, it took a few days of my spare time to get the files to where they are now.
