Anet A8 Plus Over the Top Filament Guide

thingiverse

While I did not encounter the same unspooling problem I faced with my Geeetech I3 Pro C on this printer, it has a nearly identical direct drive extruder, and I mount my spools on the back side near the top, as do I with the Geeetech. The only reason I didn't encounter the same problem is the 350mm ceiling helps to prevent the filament from rolling over the edge of the spool. I installed those filament guides on my Geeetech last night and they've been working fantastic, resolving a painful issue. The reason I'm installing this modification on the A8 Plus is to keep the unwound filament from landing on and rubbing on the left Z axis lead screw. I kept the 45 degree offset that I implemented on the Geeetech model, but simplified the print as it doesn't need the added height that was needed on the Geeetech, and secure this to the top of the frame with a single M4x8mm screw and M4 T-nut. **UPDATE 01132022: I was printing a tall 300mm model this evening and noticed how close my X drag chain mount was getting to my filament guide. When my print completed, I ran the Z to nearly its 350mm ceiling. To my dismay, at 330mm, the extension for my chain mount touched the filament guide. I extended the height for my filament guide by 40mm so that it would clear my drag chain assembly, and not kink filament with the Z at 350mm and X at 300mm. The new model is labeled "Tall" and allows the full build volume of the Anet A8 Plus with Juh's "Lightweight and Unobtrusive X-axis Cable chain". I left the original model for those who aren't using that drag chain design.
