Review on BATIGE USB 3.0 & 3.5mm Car Mount Flush Cable - Waterproof 6ft Extension for Car, Boat & Motorcycle by Vince Dickey

I used adapters on my slot machine. I have reviewed this BATIGE product in great detail. It is on the product side with two 3.0 ports. So you can go there to read it: https://www.amazon.com/gp/product/B07C75L5V3. I'll just give you a brief overview of what is. Adapter = Drill 30mm and Dual USB 3.0 Adapter = Drill 30mm. 30mm = 1-3/16" (fraction). I'll give you a link to the drill bit I used. It works well and costs a few bucks. Comes with Amazon Prime. I made 3 holes with this 1 bit , and the drill looks like it can cut more and more holes. /product/B07R7TJ78V And you're done!
