About this 3D model

UPDATE: Fixed a few lines of code which made things wonky if you change the dimensions of the walls. Inspired by Nophead, I wanted to implement his ideas for Mendel90 into a printer design. I made an OpenSCAD script to generate the mount for his linear bearings. Hope it comes in handy to someone. Check out NopHead's blog. Its the best! http://www.hydraraptor.blogspot.com/ My design could be significantly optimized, but it does work.
