Replacement Syncro heel for Nordica flex 67 ski boot

Replacement heel for Nordica flex 67 ski boot.

The original heels were marked:
-SYNCRO-1 225/305
-SYNCRO-2 225/305
but except for the marking they seemed to be identical

I made some modifications comparing to original heel, mainly made everything thicker because i was afraid it could get damaged during skiing.

Printed at 100% infill

Make sure to lay the heel flat on the buildplate. Otherwise you will end up with big useless support.

Use at your own risk.
I'm not responsible for any harm caused by print breaking during usage.
