Toyota 1MZ-FE/3MZ-FE Cam Seal Press Tool

You must scale this design up according to how much your 3D printer setup shrinks, typically about 10% for ABS. This design is created to machine-tight tolerances - it's now your job to ensure the inner diameter is at least 1.5 inches to clear the spindle. This quick and easy tool helps evenly seat camshaft seals in a 1MZ-FE engine - it will also work for the 3MZ-FE, and likely many other Toyota engines. It snugly fits over the spindle for pulleys and gets pressed down onto the seals by driving it down with the camshaft's own bolt. The rear camshaft is an absolute pain to reach in a Highlander - there's minimal wiggle room to work with - so tapping anything back there with a hammer won't likely work. After seeing videos of people using a similar branded tool, I created this design for quick access to evenly press down camshaft seals. Since there's no equivalent design on Thingiverse for these engines, I'm sharing the love for other DIY mechanics who might need it now. This tool is designed to be printed without supports - I printed mine in ABS at 30% infill and 15% oversized to generously compensate for shrinkage.
