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.

Supplies

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

Step 1:

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".

Step 2:

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.

Step 3:

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

Step 4:

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.

Step 5:

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

Step 6:

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!
