Traxxas Slash 2WD Part 2555 Modified Rear Suspension Arms

thingiverse

Update: Also see part 3631 for front suspension arms. PLEASE READ ALL NOTES. I'm extremely proud of this part, which took me several weeks to optimize. Any feedback from actual field testing and pictures of breakages will be greatly appreciated. Please keep me in mind and help me improve this part for all the bashers out there. Part v11 is an 11th generation part that takes into account breakage data and feedback from Karnite. It has fewer holes at the breakage points, plus the chassis screw encasement is just a bit reduced at the outer ranges of its swing. Part v10 is a 10th generation weight-reduced part with the thickest ends possible around the chassis pins, which hasn't been field-tested yet but I believe it will be super durable. Part 10 has left and right versions. Its weight is close to factory weight but maybe 10% heavier. Part 82 is an older solid version, field-tested, and quite a bit heavier than the Traxxas part. This part broke around the chassis pin when I did a 6' tall ramp, so I made version 10. Any thicker and you will need aluminum or a different printing material. I use this with the low gravity kit for the Traxxas Slash 2WD. I start by screwing the longest chassis pin in at the back end of the car (backwards from Traxxas), and start the shorter wheel pin at the front end of the car (same as Traxxas). This allows me to replace the part much easier when it breaks. Please print this with PLA as solid (90% density) on high-quality setting. Use supports to ensure the holes are round. Use a 1/8" drill bit to clean out the end holes for the pins and a 1/16" or 5/64" to clean out the middle suspension screw hole. DO NOT OVERSIZE the holes, which weakens the part! If you use a 5/64" for the suspension hole and it's too big, then try heating around the hole for a couple of seconds with a lighter or small grill torch, then squeeze above and below the hole with pliers to make the hole smaller. I created this part because the Traxxas original suspension hole kept stripping out. Filling the hole with super glue then re-drilling the hole nice and small can also work sometimes.
