This should work for watches that use a 24mm band, such as the ticwatch pro 5. Works with the quick release pins to connect to the watch.
If you don't have any from another watch band, you will need 2 24mm quick release pins.
The clasp just pushes together and will probably wear out after a while, but I didn't have it in me to design anything fancy for it yet.
You'll need to print the following, the reversed models are provided out of convenience and to help unify the texture from your printbed.
1x watch band clasp
1x watch band end link
1x watch band end link (reversed)
1x watch band connector to watch casing
1x watch band connector to watch casing (reversed)
adjust the number of regular links to print based on your wrist size. I have an approx 8.5in circumference wrist (large), and needed to print 12 of these
Pin part A and B - print one set of these per connection needed - I needed 14 sets - you may want to print a few extra, if any part will break on assembly, it will be this.
Assembly
(clasp)-(end link)-(regular links)-(connector to casing)-(watch casing)-(connector to casing reversed)-(regular links)-(end link reversed)-(clasp)
Each piece is connected with the pins. Insert pin part A through the watch band links, then insert Pin part B into the other side - it is a tight friction fit.
Future design plans:
remix for 22mm and other sized watches
redesign clasp
The author remixed this model.
This is a heavily remixed version of the bracelet linked here.
I adapted it to be wider, added links to connect to a watch, made the clasp work from both directions, and redesigned the pin to be a 2-part friction fit pin
