Maker Select/Duplicator i3 Spring Guide

thingiverse

I modified my Maker Select to use 3-point bed leveling and noticed that the heated bed wasn't as stable in relation to the Y-axis carriage due to a lost connection point and spring movement. The two-part spring guides prevent unwanted rotation/translation of the heated bed without interfering with bed leveling, making them a simple yet effective solution. These guides would likely benefit 4-point leveling setups just as much. The top guide piece should be installed with the nut already in place and tightened to ensure a secure fit. Depending on your printer model, you might find the height I've designed these at to be insufficient or too great. In that case, simply scale the Z-axis in your slicer software or let me know and I'll upload some alternative variations. If you're considering making the switch to 3-point bed leveling, I highly recommend it.
