Simagic DS-8x tension knob

This is a knob designed to be used with the Simagic DS-8x shifter.
Instead of having to remember where you put the allen key to adjust the tension on the Simagic shifter, or fiddeling to adjust while driving. Just have this knob stay in the tension bolt.
I adjust the tension every time i switch between sequential and h-pattern. The allen key is too big to just stay in the shifter, and having to find the adjuster was getting anoying.

So I decided to find a solution to my biggest problem with the shifter.

Use either pla+ petg or stronger.
3-5 perimeters
30-40% infill. I prefere honeycomb infill.
0.15-0.2mm layer height
No supports

It's a tight fit by design,to reduce the chance of it getting lost, or falling out. I have mine permanently installed. if you want it a bit looser, just change the size to less than 100%.
95% should be enough if you want it removable.
