I wanted to make improved parts over the stock aluminum parts you can buy. These parts are all 3D printed and should be lower cost than the aluminum parts. Assuming you print them yourself. My goal was to add some safety around the gears and make it strong. I use a heavy duty Manfrotto tripod. I bolt a camera “cheese plate” directly to the tripod and lock in place with the 3 screws locking built into the tripod. the cheese plate from Amazon was a mix of SAE and metric measurements. I bolted the cheese plate to the tripod 3/8-16 mount bolt. Previously, I use the Manfrotto ball head and a 3d printed locking plate. I easily broke it with 20% infill. So, this part of the assembly needs to be very strong. I printed the whole project in PETG, with 40% infill. Various M4 hardware will be needed. Some M3 is needed to mount the buck regulators and the arduino.
Link to cheese plate on Amazon. A similar plate should work okay to match your tripod and 2 parts mounted onto plate.
