Anet Z-axis top with bearings and filament guide

thingiverse

Ever hear a blood-curdling screech emanating from your z-axis? The culprit is probably the leadscrew scraping against its surrounding acrylic. Here's a foolproof solution to rectify that and boost printing precision. This replacement for the original acrylic piece cradles the z-axis rods, boasting an ultra-tight 8mm chrome rod radius and a 608ZZ bearing with a snug press fit, eliminating any z-axis wobble during print runs. The right-hand component boasts a boss that accommodates filament passage, plus space for a bowden tube to prevent material re-spools, although some filing might be necessary for a perfect fit. Replacing the cheap acrylic piece is child's play – no extra fasteners required. Print Settings: Printer: Anet A8 Rafts: No Supports: No Resolution: 150-250 microns Infill: 30% Notes: If you prefer the filament guide on the left side, simply mirror the parts in your slicer. Mounting remains unchanged – just flip the parts. How I Designed This: I reverse-engineered the original acrylic piece and added a filament guide. After several months of usage, I realized adding a bearing would better eliminate z-axis wobble, so that's what I did.
