Anycubic i3 mega - Yet another Z axis anti wobble stablizer bearing leadscrew

cults3d

Z axis leadscrew anti wobble for the i3 mega. It's a two piece design inspired by other designs found on thingiverse. The top piece needs to be somewhat flexible such as printed in nylon or Pla plus to be able to clip it onto the frame. Also you may be able to heat up the part with a heat gun to allow it to flex into place, might try it with regular PLA if it doesn't want to go on. The Z wobble comes from the coupler grub screws that tighten the leadscrew. Hopefully the two bearing design will eliminate that. A solid couple that clamps around the leadscrew is much better at limiting the wobble, similar to that found on creality machine couplers. I'm still putting my machine back together with the mods I'm doing to it, so I haven't tested it yet. Seems very solid though. The bottom screws are M3x10mm with a washer. The top just clips on. Bearings are 22mm 608 skateboard bearings.
