Parametric Linear Rail

This is a parametric design of the rails used for 3DPRINTINGWORLD's linear bearings published here: https://www.thingiverse.com/thing:2816093. THIS IS A WORK IN PROGRESS!While this prints and functions well, some of the parameters aren't quite right and I'm having a hard time with getting the mounting holes centered if you add more than 3-4. I am open to feedback from anyone with more experience with SCAD designs as this is my first try. I'm in the process of making a spice rack that slides out from the cabinet and needed a drawerslide but don't want to go to the hardware store to buy them. I saw this design years ago as part of 3DPRINTINGWORLD's Mulbot printer but the rails weren't quite the right size.It prints easily and the bearings just use regular .177 bbs so they are easy to get ahold of. This model is only the linear rail, the carrige and endstops that need printed for this are found at 3DPRINTINGWORLD's thingiverse page.Boost MeDid this design w
