I designed this based off of my Tronxy P802MA printer and I can't guarantee that it will work for others. There is a piece for the left and right side so be sure you pay attention when adding them. Each piece is 10mm in height and holds a single 608 bearing. It's a tight fit so you'll need to press or hammer the bearing in. The Z wobble upgrade attaches to the 8mm guide rod, the 8mm lead screw and the 3mm screw that holds down the piece on top that secures the guide rod. The center of each of these holes is 17mm apart, creating an equilateral triangle. This fits my printer perfectly but you can use the Tinkercad file to make changes if yours is different.https://www.tinkercad.com/things/7IeIgmBBuYe To install - Press the bearings into the Z wobble upgrade pieces. They need to be flush with the top. Unscrew the 2 screws on each side that hold the top pieces on. Lift each piece up enough to pull the lead screw and guide rods free. Gently press the side with the bearing over the lead screw to test for fit. If it's too tight, use sandpaper on the inside of the bearing by wrapping a small piece of sandpaper around a smaller tube like a screwdriver shaft. I only had to gently sand less than a minute with 320 grit paper. There is a left and right piece! Once the fit is right, press the upgrade part over the guide rod and lead screw. You might have to wiggle it a little to get it to go down. Make sure you press it down far enough so that the guide rod and lead screw can fit back into the top piece. Tighten the screws that hold the top pieces down.Replace the piece that holds the guide rod in place and insert the screw. The upgrade piece should be able to hold this screw tight without a nut. The screw hole is smaller than 3mm so you may need to use a little force to get it started. Don't strip it by over tightening.
