3D Printed Walking Quad Robot

Here's a simple quadruped robot I made to demonstrate how to use a battery holder for 2 AA batteries. The 3D print is easy, with no supports needed.

1. DC Motor
2. Wood screws
3. Wires
4. Screwdriver
5. Battery holder for 2 AA batteries

STL files:

1. Quad-Body.stl x1
2. Quad-Foot.stl x4
3. Quad-Hub_10mm.stl x10
4. Quad-Hub_13mm.stl x4
5. Quad-Leg.stl x4
6. Quad-Lock.st x12
7. Quad-Rotor.stl x2
8. Quad-Separator.stl x2
9. Quad-Shin.stl x4
10. Quad-Washer.stl x18

Attach the 4 "Quad-Shin.stl" to the "Quad-Body.stl" with the screws, "Quad-Washer.stl", "Quad-Hub_10mm.stl" and the "Quad-Lock.stl".

Rotate the assembly downwards to secure the battery holder and DC motor to the "Quad-Body.stl" with screws. The screws should not extend too far into the motor body to avoid touching the gears.

Connect the motor to the battery holder with the wires.

Assemble the "Quad-Leg.stl" with the "Quad-Rotor.stl", "Quad-Hub_10mm.stl", the "Quad-Washer.stl" with screws

Attach the legs to the "Quad-Shin.stl" and insert the "Quad-Rotor.stl" onto the motor shaft.

The rotors must be aligned on opposite sides of each other.

Repeat step 3 to assemble the legs on the other side.

Attach the "Quad-Foot.stl", "Quad-Washer.stl" to the "Quad-Leg.stl" with the "Quad-Hub_13mm.stl" and screws.

Put 2 batteries AA and enjoy it!
