Sigma 906 counter reset button replacement

Lost button on my cycle computer Sigma 906 (sold also branded as Force F9) so had to replace it.

Model is top right button for counter resetting, for top left one just mirror the file appropriately.

This is second revision which is, for me, good enough. As seen on photo it don't exactly match with original button, but will work on it if needed replace it again.

Source file included, feel free to fix it.
