have done some research but i am stuck on some things.

1) to print RC parts (remote control like traxxas, parts), would nylon be the same strength and durability? https://www.tomsguide.com/us/3d-prin...ews-24392.html

2) to design something, it seems the cost of the software is more expensive than the machine. is there a cheap option?

3) slicing program - what do you guys use and price.

i know there are millions of files out there, so i may be able to find the RC parts (files) that i need to replace.
