Nút kéo cho khóa kéo túi xách

Edit

The standard piece has a 0.2 clearance in the carabinier, in my case it opens just fine after a little initial resitance, but I added 0.3 and 0.4 clearance versions in case the standard ones bind too much on different printers/settings.

The cut is angled to prevent the carabinier from opening from the inside, but of course, the tighter you can print it the better.
