Flexible watch band with integrated buckle that prints as part of the strap.
This is the plain version of http://www.thingiverse.com/thing:1678181 - I haven't actually printed this band myself yet, but I've included sldprt files in case you want to customize.
Designed for a Pebble Time Round, but will fit other watches with 20mm band.
Needs to be printed with ninjaflex or other flexible filament. You'll also need two 20mm spring-loaded watch band pins from another strap or purchased from a jeweller.
Print 2 copies of the strap loop.
This is the first version of this design, so if you have any suggestions / requests, please post a comment and I'll do my best to incorporate them in the next iteration!
A few tips for printing:
- 100% infill seems to work best
- Setting minimum time per layer to a reasonable value (5-10s) can help avoid the peg part of the band fastener coming out melted-looking
1. Clean up any rough spots
Using a craft knife, cut off any left-over blobs of plastic etc., especially from the inside of the band (the side that will be against your wrist) as these can be uncomfortable if not cleaned up.
2. Attach band loops
Put both of the rectangular band loops onto the buckle side of the band. There are a couple of small tabs on the side of the strap which are meant to hold one of the loops in front of the peg.
3. Attach bands to watch case
Take a spring-loaded watch band pin and put it into the hole at the end of the strap.
If there is any excess plastic left inside the pin hole, you may need to clean it out first. I used a 2mm drill bit for this.
Put one end of the pin into the hole on the watch case lug, and use a pocket knife or other implement to compress the spring-loaded pin enough that it can fit inside the other lug. Make sure it lines up with the hole - it should click into place.
Repeat for the other strap.
4. Fasten watch band
With the watch on your wrist, pass the end of the long strap through the hole in the end of the other strap, then through the first band loop and over the top of the peg. (This can be a bit fiddly, I'm trying to think of improvements to the design in this area)
Tighten the strap, and push the peg through one of the round holes running down the centre of the strap. Then push the end of the long strap through the second band loop.
