Neutrik, which is commonly used in DIY fight stick kits, uses a USB-B printer cable to connect to the fight stick itself.
This mounter eliminates this problem and allows you to connect the Fight Stick to a PC or other device using a USB-C to A cable, which is often used to connect smartphones.
By using this, you can use your own portable USB-C to A cable.
The mounter simply uses a common hole saw to drill a hole in a metal, plastic, or wood panel, inserts the panel mount, and tightens it with screws.
The size of the hole is 21mm, but the 24mm hole provided for the Neutrik can be used as well since it is threaded.
