Default 1/8 caster block and spindles

I am designing some caster blocks and spindles for a 1/8th nitro buggy. Curious on suggestions for material to use for these parts. Petg, Pla?? If they are successful I will have them machined from aluminum, but wanted to print them first for testing purposes.

If you are just fit checking etc just some standard old PLA will work fine.. For something printed to hold up to 1/8 scale duty I would start with something like Polycarbonate , or just cut straight to the chase and go for some CF/Nylon.

Pretty much any 3d printed part will be weaker along the Z axis. This sometimes can make orienting a part difficult if not impossible based on the stresses it will receive. I once tried unsuccessfully to print a chassis mount for an old Losi XXX-T. It was fine if you went over a small jump square, but as soon as you landed crooked it would break.

What does success mean to you for a 3d printed part?
