Maker Select/Duplicator i3 Spring Guide

After modifying my Maker Select to use 3-point bed leveling I noticed that the heated bed was not as rigid in relation to the Y-axis carriage due to the loss of a connection point and the movement of the springs. These simple two-part spring guides prevent unwanted rotation/translation of the heated bed without interfering with bed leveling. I'm sure these guides would benefit 4-point leveling setups as well.

The top piece of the guide should be installed with the nut already in place and tightened. Depending on your printer you might find the height I have designed these at to be insufficient or too great. In that case you can scale the Z-axis in your slicer, or comment and I'll upload some variations.

To anybody thinking about making the change to 3-point bed leveling I definitely recommend it.
