Fitbit Charge 4 excess band loop replacement

Fitbit Charge 4 excess band loop replacement. I broke the band loop on my charge 4 for the second time so I had no spares to use.
The band loop is about 22x5x8mm(inside dimensions)x1.6mm thick with a small nub inside to help it hold position using the the bands slots.
Works well and only 10 minutes to print at TPU speed.

I hope someone else finds this usefull.

Charge 3 bands also fit Charge 4 so is probably good for Charge 3
