How much infill do you print with a part like this? I'm familiar with the truggy tires, I like those to be soft so I use thin walls and they print hollow per design; this seems to be more solid?

The lower the better, try 10% to see if that works for your setup

Is there any tips for printing it successfully with PI-ETPU filament? I have tried with many different setting with my printer Prusai3 but is vain.
Since it is very soft it gets twisted and tangled up after the it's pushed by the gear. I am so frustrated.

Thanks for trying out my filament Joohyun :- ) Sorry to say I have no experience with Prusai3. Please read through this page: http://rubber3dprinting.com/how-to-3d-print-flexible/ Also found this topic here on thingiverse: https://www.thingiverse.com/groups/prusa-i3/topic:6655 And this mod might help you? https://www.thingiverse.com/thing:553406.

in short:
if the tension on the gear is very big on the filament it will bend easily after the gear - loosen pressure
feeding to fast? - start at 5-10mm/s
temp - use the max 230 deg C
Nozzle size - bigger nozzle will be easier
if the support under the gear is bad - minimize the gap and best use PTFE tube

Hope you will succeed, good luck! KR Thomas
