This is what I call a glove backbone. It holds the form of your glove while in your bag or anywhere you take it.

    Keynotes

     You will need a heat gun, but it could work with a hair dryer on a high setting. Be careful not to heat it up for too long, as it can melt any plastic you use. The mold should be flexible enough to be shaped without collapsing in on itself.  This will also be outside, so it is better to print in PETG or ABS; however, PLA can work but can have the risk of melting if left in the sun too long.  Supports are needed.
