So i have a pi. Or a few pi's. A few years back i bought 12 or more pi's and set them up with retro pi and controllers and gave them out as Christmas gifts. So i am not dumb to what a pi is or how to use it. I just rely heavily on youtube tutorials because i am a mechanic and not a programmer. I now am playing with octoprint and have sucessfully installed it on a pi with 5v relay for printer power control and a 8mp pi camera. I have all of these things up and working nicely. I just want to install this 3.5" touchscreen I got from ebay. This touch screen right here: https://www.ebay.com/itm/New-3-5-HDM...53.m2749.l2649

And to install it I am following this awesome tutorial:

The tutorial shows typing in a command to make the pi go to a website and download a driver. The ebay ad does not come with the same style link for me to copy and paste. I can goto a website on my pc and download the link and have it in a zipped file But I am at a complete loss for how to get this touchscreen to work with my pi. Any help would be greatly appreciated.
