Plastic Monstrosity CNC Build

First off, *THIS IS A REMIX/MAKE, NOT A NEW DESIGN!* I take **NO credit** for these designs and I am posting this in hopes that others may benefit from my trial and error on the plastic monstrosity design! Note: I have created several different parts that I believe will work better than the original designs.

Thank you to Spiffcow and oscarthompson for designing the original and the remix that I used! these parts seem like they're going to be absolutely solid.

Note on product links: I use affiliate links for Amazon.
