Sony SmartBand2 DIY wristband

I've had a Sony SmartBand2 for 1.5 years now and the original wristband broke a while ago. I didn't want to buy replacement wristband (don't even know if they can be purchased), but decided to see if I could 3D print a replacement that's good enough. For the band I did a search and Emmett's nice openscad module was what I went with and it's working very well.

The unit holder part could be bit more round and bit smaller, but since it's working fine so far, not in a hurry to do anything to it.
