Pinion Correction Shim

SummaryBasic 3D model (OpenSCAD) for making typical pinion or caster angle correction shims for a leaf spring vehicle. User can specify width, length, thickness, angle, center hole size and also type of mounting. First photo is an example of a typical early model Jeep shim with 1-3/4" width, 4-1/8" length, 5/16" center hole and in this case 4 degree angle. This model file would serve 2 main purposes:First, would be to make a 3D printed shim, perhaps to try out varying angles with the vehicle stationary, in order to correct u-joint angle(s). Then, once a particular shim design is worked out, that 3D printed part could be used as a sample to machine a shim out of a more durable material like steel. You DO NOT want to run a 3D printed plastic shim while driving, that isn't safe.Secondly, you could export a STEP or IGES file and upload that to an on-line machine shop for a quote on producing that part. Or, if you have a local machine shop or know someone that has access to
