Anycubic Kossel Heated Bed Leveling Mounts

This is my first attempt at designing. I would appreciate any input/advice.

Inspired by 5imR's bed mounts, I decided to start learning openscad and design a variation that would allow for adjustments directly in line with the x, y, and z towers. The bed-supporting extrusions are 120mm to center, and the bed mounts are 30mm wide. 120 - 30/2 = 105mm from the end of the extrusion to the side of the mounts on either side. The design/code aren't all that pretty, but they definitely get the job do
