What infill for parts that need to be strong?

Question

Working on some mounting brackets. These are gonna hold actual weight so they need to be sturdy. Right now Im doing 60% infill with 4 walls. Is that overkill or should I go higher?

Try printing at 245C with 70mm/s. That's my sweet spot for PETG.

You'll want to use PETG with at least 0.2mm layer height. Works way better than PLA for car parts.
