Anti Z Wobble for Anet A8 688ZZ bearings

thingiverse

This is a remix of http://www.thingiverse.com/thing:1858435. I had initially planned on making these, but only had 688ZZ (8x16x5mm) bearings available, so I created this remix instead. Version 1: The same style as the original design, with the other bearings used in place of the originals. The guide bar can still rotate and the rod may continue to wobble, at least that's my assumption. Version 2: The hole for the bearing is now flipped to the opposite side. The rod enters the bearing slightly, leaving some space at the top. I've included pictures to illustrate this design. With centering bolts inserted into the 10mm holes, the rod can enter more smoothly, and there's no wobbling to worry about. Print Settings: Printer: Anet A8 Rafts: Doesn't Matter Supports: No Resolution: 0.1mm Infill: 70% Notes: For saschai's design, print Version 1. For the design with centering bolts, print Version 2 and "Zentrierstift". You'll need to print this twice because you'll require two Z-axis rods. I printed the Anti Z Wobbles with a 5mm brim. It may not be strictly necessary, but it's worth trying. After printing, you might want to scrape the tiles to ensure a better fit for your bearings.
