I printed the model from Luckystrykx and have to say I didn't like the feel with the gap on the side. It had sharp edges, so I used Meshmixer to smooth it out.
I recommend printing it at 97% in PLA because it does not shrink as much as ABS. Also rotate it 45° to the back and print with a raft to avoid sharp edges at the bottom.
As soon as I printed it, I will upload a picture.

Update:
I printed the grip in red PLA with 97% scale and it fits like a glove! Very nice surface thanks to the 45deg orientation of the part.

Happy printing!
