Printed this on my Prusa Mini with prusaslicer using the Saint smart tpu setting, when the print start just drop the speed to 80% on your printer and the result is amazing. this handle bar grip fit on 22 mm handle perfectly you will need a bit of glue to prevent it from turning. the hole is 22.35 with a 1 mm filet to help fit on the tube. Hope you like it, please post a photo of your print if you are satisfied with the result. I have made this STL for a kid scooter
