Quick connect for the RC4WD / JD Models / Eagle Machinery 870k wheel loader. UPDATE: new "plate.stl" now with more servo support. UPDATE 2: New "AccApapterBiggerHook.stl" part with more hook to avoid "popping off" with heavier loads - thanks Chris for your testing! To complete, you will need the following: * 6mm stainless rod (Amazon): https://www.amazon.com/gp/product/B072JPQX4Q * Spring set (Amazon): https://www.amazon.com/gp/product/B07RFH9Y74 * Flanges on the end of the locking rods - a buddy tig welded some washers on there. As shown in the photo, these are about 33mm long. * I used a Hitec HS-85MG+ but you could use another similarly sized servo - you'll need to cut up a horn to fit in the recess under the cam part. * 16 Stainless M3x10mm screws, counter-sunk. I think they're all 10mm in length, but if you get the assortment from Amazon, you're sure to have several lengths, and 4 nuts (again, the assortment will also have nuts). Assembly is pretty straightforward. It's fairly strong for what it is, but I make no promises about long-term durability. The only metal version available is quite expensive, then you either have to modify your stock bucket or buy new ones. I may design a bucket; it would be interesting to see how long one would last if it were printed out of nylon or something else that's stronger than PLA.
