finger for EEZYbotARM mk2

For a specific installation - the robot will be playing a miniature toy piano - I was in the need of a moving finger. Here it is.
It fixes itself on the arm of the fantastic EEZYbotARM mk2 - uses the same SG90 servo motor - I replaced the screws with standard m3 bolts, because servo screws are mostly too fragile.
The part EBAmk2_016_claw_gear_drive is additionally needed for the servo arm.

PS : yes, I'm quite new to 3d programs - it's a mess of a mesh ;)
