Replacement Knob for Volvo Special Tool #9995454 B 21

Hello,

This is something quick I threw together. This is intended to replace the knobs found on the Volvo 5 cylinder B5254 valve cover holding tool. The original plastic knob was broken, and a bit finicky to use. So I built this as a replacement. It's a friction fitting design, which can easily be installed by tapping the knob with a mallet or pushing hard against a wall. I would strongly recommend using something like PLA or PETG at 99% infill. Just to be sure the part doesn't break upon installation.

If you end up using this, please leave a comment! I would love to hear from any technicians or DIYers that found this helpful.

Thanks!
