Olympus E-M5 mkII camera grip

The original grip design is by Scott Garriott, you can find his model at https://grabcad.com/library/e-m5-mkii-diy-camera-grip-1
I know EM5mk2 is a 2015 camera, I use my design for a long time until my friend ask me to share it.

I tweak some detail:
1. The Garriott design bottom is 6 mm, so many tripod plate can't reach. My design reduce to 2 mm. Of course it will become more fragile. So it is suggest to print with high strength material.
2. So I increase the "front bumper" thickness
3.
