    Hey guys

    Ive been running the mp3dp for a few weeks now. Im using zip ties on the lm8uu bearings on the y axis bed. Theres a little play/wobble that i think might be affecting the quality of my prints (vibrations maybe). Any suggestions to make the bed a little stiffer?

    Print three of these and install in existing holes, they match perfectly.
    Use m3 machine screws and nuts.
    No more wobble!

    I modded mine by changing to four linear bearings in a rectangle instead of three in a triangle. The Y is so much smoother and no longer has the wiggle it had before. Before I did that I tested some graphite impregnated brass bushings, but they introduced too much drag, the belt would skip.
