This is simple 3Dp beginner project for every one that has access to 3D printer.
Additional what you need is:
- 2x servo
- Arduino/Raspberry Pi or any other programmable platform to control servo
- xylophone or similar instrument (you can also improvise ;) )
Step 1: Base
Grab files from http://www.thingiverse.com/thing:1379539
If you have Servo "hex tronik hx12k" or other same dimensions you can directly print
For other servos insert your dimensions in to servo1.scad andgenerate stl file using OpenScad
Step 2: Top Servo
If you have Servo "hex tronik hx12k" or other same dimensions you can directly print file "hex_tronik_hx12k_servo_top.stl"
For other servos insert your dimensions in to "servo2.scad" and generate stl file using OpenScad
Step 3: Assemble
Now you only need 8 screws to screw the top and bottom servo,
and press fit the top servo to bottom servos servo horn.
To reduce stress to the servo, the "drumstick" is held only by rubber
If your base is to light drill some hole and glue in some heavy material
or use some tape.
