AM8 E3D Extruder with Filament guide

thingiverse

I recently added Denos' AM8 spool holder to my printer (Link below). I liked the function and design of this holder so well, I didn't want to give it up when I upgraded to an E3D V6 hot end and remote extruder. The problem was that the extruder needed to be as far as possible off to one side and the spool holder dispenses the filament at a 90 degree angle. So I created this Anet A8 remote extruder mount which puts the extruder as far to the left as possible (right over the left upright). It also has roller bearing filament guides to route the filament from the back of the machine 180 degrees to the input of the extruder. Also included is a ball bearing guide that sits under the spool to reroute the filament 90 degrees toward the extruder. The bearings are 608 Bearings which are exactly the same ones used in Deno's spool holder. You can by 16 on Amazon for about the same price as 4 so I had extras. When installing new filament, feed the filament into the guide under the holder. The guide will direct the filament through a 90 degree turn and out through the right spool holder. The cap for the extruder frame can be rotated to make it easy to put the filament in place after starting it through the extracter. Thanks to the bearings and gentle turns, the filament pulls almost as easily through the guides as it does directly from the spool. The guide is small enough to allow it to work with small 500g as will as the 1KG spools. The only weakness I've seen in the design so far is that the horizontal roller can ride up slightly and allow the filament under it. I may need to add a bolt hole in the horizontal cover to keep it clamped down. Update: July 17, 2018 Since my original posting, I continued to have problems with the horizontal roller on the spool guide floating up and letting the filament under it. I have since fixed the problem by removing the horizontal cover (AM8_Extruder_Filament_Guide_H_Cap_V9.stl) and just putting a bolt through the bearing to hold it down. As an added bonus, I like the way it looks without that cover on it! Denos Spool Holder: https://www.thingiverse.com/thing:2537713
