Z axis anti wobble #2 for Geetech Prusa i3 X (27mm rod sep.)

thingiverse

It's not an arc reactor; it's just improved printing technology. If you have loose z-nuts, use this instead. It reduces the z-wobble, but doesn't eliminate it completely. I'm still investigating why my wobble persists. Typical anti-z-wobble gliding discs are a good option if your nut has no play. Three versions are included: one for an 8mm smooth rod and another with a 27mm rod separation. It's suitable for 8mm threaded rods and TR8x1.5 threaded rods, both with an outer diameter of 22mm. vB Version: For TR8x1.5 threaded rods, it has a reduced outer diameter of 20mm. Addon: To attach the Wobble-thing below the upper acrylic plate, print this addon separately and mirror its second part for proper alignment. The reasons for periodic z-wobble include: Bent threaded rods Eccentrically mounted threaded rods Play between the nut and threaded rod Tilted threaded rods This printed thread has no clearance. Six flexure-bearing based threaded clamps ensure smooth rotation with minimal friction, compensating for variations in rod angle and diameter. The common gliding feature is built-in. Moving this thing by 1mm in the x-direction changes z-height by 7 microns for an M8 rod, which is equivalent to 3.5% of a layer height of 200 microns. Print Settings: Supports: None Notes: Add manual support for the addon by cutting a hole and removing the supporting central part. A version with no supports is also included. Print the second addon mirrored to avoid interference from screws. Post-Printing: When assembling, be careful not to crush these things against the motor coupler. They might break. Apply lubricant like Silicon spray, PTFE spray, or MoS2. Alternatively, use a rubber o-ring or cable tie to tighten the clamps. Assembly is observable in the provided photo.
