This is a 26 mm watch strap based on the original one from the rather rare Abardeen F80 watch phone/smartwatch.
Not long after I designed and printed a replacement cradle for this watch phone, the original rubber band also began to disintegrate. The solution was obvious: print a new one! I copied the design so I could reuse the push pins, buckle, and tab from the original strap. Printing my own strap allowed me to create a shorter one that better matches my wrist, so it is a double win.
I used flexible PLA from rigid.ink. This needs to be printed on painter's tape because getting it off any other surface is an ordeal, especially BuildTak. However, as you can see from the photos, the texture of the blue 3M painter's tape causes a very nice ‘faux leather’ look, which makes this strap look a lot more stylish than the original!
The tab to prevent the end of the strap from flapping around, also broke a while later, so I printed a new one as well. I used PETG which is ideal for this, because it is extremely strong and durable.
Because it is so unlikely that anyone else will have the exact same strap with the same clip design, I also included the Blender files so it is easier to remix.
0.2 mm and 0.1 mm (catch)
Added v2 version with some more rounding.
