I made this with simplicity in mind. The leg design does not use any extra screws. You only need the screws that come with the servos. I highly recommend using all metal gear mg90s servos otherwise the servo horn will not fit properly into the 3d print. The quadruped uses an Arduino Uno with a servo driver shield to control the servos and a NRF24L01 radio module to control it. The hexapod uses an Arduino Mega with a prototyping shield. You don't need a servo driver to control the 18 servos. The Mega has plenty of pins. I also used a NRF24L01 radio module to control it. I am using a Creality Ender 3 to print the parts with PLA. The resolution should be set at 0.2 (however you could probably print them at 0.3). Use 20% infill, I like to use the grid pattern. Lastly, you should set the over hang angle to 76 deg.
