MUCH!! THANKS to RamjetX https://www.thingiverse.com/thing:3366188/comments/#comment-2386946 He solved all the electrical issues, THAT was indeed the hard part. Without his post, i wouldnt have a loac cell setup, so BIG THANKS!! I have T3PA PRO pedals, and stock, they have a small tray that holds a spring, or it has thread to hold a rubber bumper that threads into the tray. I am using the tray because it has convenient mounting ears & screws to attach it to the pedal base ;). I only use 2 of those mounting screws to attach the tray (FYI) and dont have any issues so far. Time will tell i suppose. This will require a spring. Mine came from a broken umbrella. My guess is its probably around 80lbs, or twice what the load cell is rated at. I have not created the brackets to hold the spring elegantly in place, yet. Presently it simply stays between 2 screws. I took a few pics with the spring removed so you can see. The screws use holes already available in either the load cell or the Pedal. The small black disk on top was just a metal nut that fit the inside of the spring. YOu dont need it actually. These load cells have 2 screws on each end, they are different sizes. Because of how the load cell wires are siliconed to the side of the load cell, I had to mount via the smaller holes. The hole on mine was M6, and the length needed was 35mm. The second hole just above the one used to mount it, is potentially important. Look at the images of the loadcell mounted. You will see a small black screw sticking up. A load cell works by measuring the flex in the aluminum bar. By placeing a screw for the brake arm to run into, it keep me from damaging the load cell by applying to much force. . As my spring is probably 80+lbs, I needed to stop the pedal travel. To adjust this, I used a laptop, and the stock windows 10 application "USB Game Controller," I just pulled the pedal, watch the game controller display till it maxed the load cell, then adjusted the screw up to meet the back of the brake arm. Its not a particular pretty thing, but presently it works. My father handed me a few Fanatec springs from his rig, and ill give them a try. SO some experimenting can and needs to take place regarding finding the right spring for me. Obviously the heavier the spring, the less throw you get. 80lb gives me about an inch of throw, so....ya i need to experiment. I am not a good designer, BUT....if you wanna download the actual cad files you can here. I hope this helps your Buddy out a little. Its certainly cost effective when you can make one for less than 10 bucks via ebay. I am NOT a good cad guy, im learning.....but https://a360.co/2EXq3T0
