Easy Fit i3 z-axis anti wobble

thingiverse

Made for my CTC i3 clone. Its was a cheap diy kit printer, came with basic 8mm threaded rod for the z-axis. To start with I was happy with the prints from this cheap printer, but over time I wanted to improve it. But sticking to the cheap and easy method. I was getting a lot of wobble on my z-axis... so decided to upgrade the rods to 8mm lead screws... but before that.... I'd go cheap (the lead screws are cheap enough anyway!). By separating the threaded drive nut from the z-axis assembly, it allows you to lose the wobble of the threaded rod in the joint. The x axis is still lifted, but any movement in the rod is not passed to the rigid x axis assembly and therefore - not into your print. Next challenge was to make it easy to fit... preferable without stripping the printer apart. This is done with 2 slots in the mount - allowing it to be passed vertically between the threaded bar and the guide rod. Then rotated flat and screwed into place. Note: You may need to sand the inside edges slightly to allow a snug but not tight fit on the guide rod. The prints are a lot nicer - I'll try and find some prints to show before and after. https://youtu.be/L-kIB3UUVME Happy making. V2 - I've added a Version 2 with nicer finished edges. V3 - I've now upgraded to 8mm lead screws - the nut was a little larger so this is an edited version that fits the larger diameter rim on the nuts. Edit - Now added left and Right parts for V2 and V3 - saves having to duplicate the part and mirror it.
