I do something similar currently. I took an old pair of landyachtz gloves and cut the thumb out of the right hand (no puck on that one) and then use the glove as usual on the left. I don’t plan on doing a ton of sliding, but want them for taking turns at higher speeds and putting the hand down for support. So left hand turns are fine, but rights are another story.
Are there stl files for that? I am very intruiged by that and wouldn’t mind testing it out.
