This is a body you can print for your Gen 1 or Gen 2 Mochi. The body is hollow and will loosely fit the Gen 1 Mochi's control board. Alternatively, you can use the rear channel to run a power cable for your Gen 2 model.

Glue the legs to the body with the glue of your choice. Arms will press-fit onto the body and can be rotated to your heart's content. Use m1 screws to affix the back back to the body.
