> 24 hourSuper quiet, barely any play compared to brass nuts. These fit my 3d printer perfectly. Z movement is not loud at all. I hear the motors themselves way more clearly over the lewdscrew nut.

> 24 hourQuieter than brass and zero lash. Yeah they wear eventually but there are six of them in the package.

> 24 hourI decided not to wait for the brass ones to wear out. sure they are self-lubricating, as they wear out, but their wear provokes the increasing possibility of backlash on a gravity-engaged moving part. These POM pieces are the worlds slipperiest plastic with the best wear rate. They are a tight fit, compared to even new brass lead screw nuts, but that tightness is not binding. reassuring is the word I would use. From what I have read, the wear properties are much superior to the brass. I retain the brass as they have not been used to the point of being worn out. The Z gantry of my 3D printer feels more substantially connected and any crew-induced motion artifacts no longer exist. Just smooth layer lines, buttery smooth and consistent. This will be a first order upgrade for any and all of my new FDM printers from now on.

> 24 hourTR8X4 works for Anycubic Mega-X. Hole pattern is good but not threaded. Need to use longer bolts and nuts.

> 24 hourVery solid and tight threads. Barely any play along the t8 rod. No lubrication needed and very quiet in operation. I have known delrin to be a very strong polymer - not easy at all to wear and cut but using this material makes the most sense to make contact with metal.
