SR20 Valve Shim Tool

thingiverse

I made this remix because I didn't want to sacrifice a lifter to measure my valve shims. I made the shaft exactly 17mm which is that max spec for the lifter holes. I printed at 100% size. Some light sanding will be required on the shaft to smooth things out since there is a tight tolerance. The tighter the better since you want the tool to move the least amount possible for measuring. The tool isn't perfect but any means but with careful markets and double checking them it will get you by.
