I pledged a Kickstarter campaign on the DOKI Smartwatch for kids. I have got mine few months ago. It is really well made, good looking and good quality. The only problem I had was the user, my son, who broke it on the second day after unbox. The watch face was shattered after a smash.
The DOKI's customer service is so good that they got my broken watch fixed. Of course, at a price but very reasonable.
So, to keep the watch at good condition, I decided to design a protective vest. It can prevent scratching and damaging to the watch face.
It will need to be printed with flexible material. I have printed it using Ninja Flex, but I think Semi-flex should do better. If any of you tried Semi-flex, please let me know.
The print speed should be very slow. I printed it at a speed of 10mm/s and nozzle temperature at 220 C.
The front face of my DOKI Vest was printed over a masking tape, so it has a kind of leather texture. If it is printed on glass of kapton tape, it should end up with a glossy look.
