I've had issues printing this in Prusa Slicer, Maker Bot's Cura is the only reliable way I've been able to print these.

Bed Temp 50C

Raft

0.1mm layer hight

100% infill

Raft with supports

Printing these stylus requires a bit of post processing and some additional work. You'll need to print this on the curve from it's end so that the lip prints right and it makes it easier to remove. The support needs to just be on the shaft.

After the part finishes printing you'll need to remove the support materials and shave off any excess.
