Tinka - A DIY 3D printable watch case for OTM-02

- Finally, a fully functional 3D printed watch case for OTM-02!

- As seen on the RepRap Community Hub (stand G54) at the TCT Show,
  25-26 September 2013, NEC, Birminham, UK.

- Designed using MoI3D.

- The design has been sucessfully printed in PLA on a
  Prusa Mendel using a 0.5 mm dia nozzle, single shell thickness,
  0.2mm Layer height, 45% Fill, 0.6 mm top and bottom thickness.
  A print speed of 20 - 30 mm/s was used for best quality.

- Two stl files are provided for the Case Body; one with and one
  without manually fabricated support structure. No other parts
  require support structure. Currently, the parts have only been
  printed using Cura 13.06.4.

- Named in honour of the family cat for her dedication to design
  supervision duties and published in the hope of encouraging more
  people to tinker with technology.

  this is only the beginning. Happy hacking.
