Yes, the scaling should be correct if I remember correctly. When I originally posted this I believe that I had the scale wrong, but I believe that I corrected this some time ago. If you want to check things, bring the gauntlet and the palm you are using into your slicing software and see if the gauntlet fits inside the palm section you used. Let me know if you have any trouble.
Thanks so much. By the way I am working on some new designs with the e-NABLE group that will be released in the coming weeks.
