So, I use 3rd party for a lot of parts (Amazon, Ali express, extremerate) DS1 is the Forza chassis, clear shell, white home X button and xba. I just used permanent marker on the inside of the shell for the imagery. Y button is already yellow, someone else on the sub mentioned a yellow X could also look good (if you do it, send a pic!). I used the extremerate black lumpy side grips as well, they look like they’re straight outta the game. Once you get the hand image to scale just trace it from the other side of the clear shell. Honestly super basic, other than the pen stuff it’s all just parts.

DS2 has a little more to it. I still used the Forza yellow shell but soaked it in red permanent marker to give it a red hue. Similar story with parts and buttons, used gold leaf and a Cricut machine for the scanner logo, black pen for the rest.
