Keep screws, battery terminals, and motor holder from the original disk/ball safe. Secure the power switch first, then connect the power wires by soldering them, and finally install the motor in its proper place. Attach the skirt to secure it firmly in position (note: this was not tested personally). Complete the assembly process. Utilize a protected 18650 cell with a button top for optimal performance. Unprotected cells are at risk of damage from overdischarging, while cells without a button will fail to make contact with the power terminal. The bottom and skirt do not require supports or rafting, but it is recommended to use supports for the battery cover.
