Improved Clamp Pads for Rockwell RK9033 JawStand

prusaprinters

The Rockwell JawStand (see https://piphardware.com/product/rockwell-jawstand/) is a handy piece of gear. Beyond its intended use as a woodworker's sawing support stand, the moderate cost and built-in 90 degree tilt clamp function has made it a favorite for sport rocket launchers and other applications where the full horizontal-to-vertical angle adjustment is crucial.This simple part is to improve the plastic clamp pads on the original RK9033 JawStand, which are undersized and made of a brittle plastic that doesn't hold up well, especially in outdoor use.  They will eventually deteriorate and shatter - see the photos for what happened to one of mine after several years.These replacement pads have about 80% more contact area than the originals.  Mount them with M4x8 stainless screws and hex nuts.  You can also re-use the original fasteners, but they are low grade and prone to corrosion.The OnShape CAD file is here: https://cad.onshape.com/documents/f18df33b058179dc8d87dfd5/w/84e499e2171ea934252e32cb/e/15ec33f07ed4797ce7181e01For more info on improving the JawStand, see my GitHub project with a parts list and instructions for upgrading all the fasteners to stainless steel and making a few other changes: https://github.com/dbcook/jawstand_upgradeMaterial: PETGNozzle: 0.4Layer height: 0.25Infill: 100%
