This is my own 12 servo hexapod design. I designed it to be modular and hence easily customizable. Want a 8 legged octopod instead? Print out some extra parts and bolt them on to your hexapod! Its thats easy. No part is greater than 10cm in its longest direction, so this should be easily printed on even the smallest printers. I designed it for the Corona CS-939MG servo, but other servos of similar size may fit.
You can see a video of it in action here:
Building is fairly straight forward. you need to print 2 of the "spine" components and 1 spine end cap. 3 of each of the leg bracket 1, leg bracket 2, leg 1, and leg 2 are required. Lastly you need 6 of the servo brackets. I printed all parts with 10% infill, 1 perimeter, and 2 solid layers on top and bottom.
The spine bolts together with 4-40 button head screws, the servo brackets use counter-sunk 2-56 to mount to the circular servo horn, and the legs us button head 2-56 (counter-sunk screws are shown in the photos, but this proved too weak). Leg brackets bolt to spine with 4-40 screws as well.
The pictures should make the assembly fairly clear. The spine has many holes spaced 8mm and 5mm apart, so you can make your own brackets to mount your choice of electronics.
