Hi, I would like to use a non-flexible, grippy filament. Any recommendations?

polyflex or ninjaflex work
Based on the chart I guess you want something like skateboard wheels, right? Any model can be printed very dense so even with soft filaments they still become almost rigid. I usually use TPU for both flexible and non-flexible rubbery grip, just by playing with the settings.

I would say hatchbox tpu witch is about twice as hard as ninjaflex but is still rubber like or tulman nylon. Nylon is hard to store because it is super moister sensitive and need high printing temps of 250+ for the extruder and 120+ for the bed. hatch box will be cheaper and easier to print with as long as your extruder has tight tolerances and is not a bowden tube. I print tpu on Buildtak and use pla settings but drop the speed down slightly and lower the build plate to 45c. hope this helps
