Traxxas Slash Front A Arm (Customizable)

thingiverse

Replacement front A arm for a Traxxas slash. All parameters have been tuned to properly fit, but if you want to change any, or if you want to modify the arm for use on another platform, the OpenSCAD file is included, and there is a diagram explaining what each measurement is. Tolerances are fairly tight. I erred on the side of too tight; the print can be sanded if needed to create extra clearance. Holes can be reamed with the hex wrench used for the screws. V1 I used ABS, 20% infill, and it felt strong. The newly printed part was lighter than the original, even though it didn't have the lightening cutouts. It held up fairly well and handled a bit of rough driving. Eventually, it broke in two spots (I will upload a picture: note to self). One of the little arms holding the wheel on snapped off completely. The other split between layers and the shaft slipped through. I imagine they broke in that order. V2 (there is a diagram showing the differences) I have - Filleted the inside of the arm that broke - Added additional material to the end of the wheel-holding arms - Added a reinforcement on top of the front wheel-holding arm - Added a reinforcement below each wheel-holding arm - Moved two vertices to strengthen the rear wheel holding arm, and the front chassis connected arm I printed this in Dual-Color Iridescent PLA, 50% infill, 0.2625mm layer height, supports touching buildplate.
