I need to service my fork recently and I found this (https://www.thingiverse.com/thing:883685) on Thingiverse, so I print it out and unfortunately; it is too big and it does not fit my cheap shock. SAD...
I then fire up my trusty CAD program and create my own. I am not sure how many people need one, but here it is. I printed it in ABS and I am sure PETG should work well too. Happy Printing.
