Nothing too fancy, I just needed to replace my handlebar grips and wanted to try something different. I built in a bulge on the throttle grip so that I can roll on the throttle using the ball of my hand in addition to squeezing it. There's other ways to do it, this is just what works for me.
Print in TPU or something soft. Fits a 22mm handlebar on the left side, and a standard throttle on the right. These are a very tight fit onto both sides, which is how I wanted, so you can scale up the X and Y axis to maybe 101% if you need more clearance.
