Infill 3D Direct Drive

Here is the Infill 3D direct drive extruder for our i3R in 1.75mm, sorry I do not have an assembled version of it to take pictures as you can guess from my previous post I prefer geared extruders however when I started into 3D printing the first thing I did is ditch the Wade extruder and build this direct drive I used it for quite a while it served me well however as all direct drives they do not do so well with irregular diameter filament, every time I ran into a problem I blamed the hotend until I figured out that it was not the hotend it was the direct drive lacking force to push the filament when it got out of spec. Since then I been using geared extruders with zero problems, with that said if we are talking direct drive extruders it is a good one.
Those holes on the bottom are for attaching accessories like LED's and fans also there is a hole that goes from one side of the extruder to the other for bring power to the attachment area, but since the SunBurn hotend has a PLA fan du
