Tomtom MultiSports ( Cardio) Wristband replacement

It's not perfect, but I do not need it, I'm not wizard of designing.
Includes a file with security band lock (I did not print this piece)
Designed for print on reverse, for show the brilliant face. Looks beautifull
I printed with -1.5mm on Z axys, and 5% infill, I have tested today in the gym and have did no issue.
It's bigger than mine ( original wrist size S ), I arrived to bed limits!
