MendelMax 2 MM2 JD Z Screw Thrust Bearing Holder

thingiverse

This is an innovative thrust bearing holder that greatly enhances the MendelMax 2 components. A significant weakness in these parts lies in the absence of a dedicated bearing to support the Z screws at the bottom, allowing them to simply dangle by spring-like helical couplers which is clearly inefficient. I found that compressing the Z screws just a bit with this part greatly improves their stability and overall functionality. To construct this thrust bearing holder, you'll need two high-quality 688 bearings, even though "thrust bearing" might be an oversimplification in this case. However given the tiny forces at play, any standard ball bearing is more than capable of performing its task effectively. One crucial component necessary for this part to function flawlessly is a well-chosen isolator and I recommend checking out: http://www.thingiverse.com/thing:750610 By incorporating this clever modification into your MendelMax 2 build, you'll see a substantial boost in overall component quality.
