Versions
MK8
- D3D first version - MK8 extruder - File:D3D Extruder.fcstd

- D3D second version - Prusa i3 MK2 Original - OSE Adapted - Extruder - File:Prusa i3 mk2 extruder adapted.fcstd
2018-06 Notes
These were noted by User:Maltfield when he attempted to build the D3D extruder from the part files on this wiki in 2018-06.
- There is a hole missing in extruder body which should receive the bolt for mounting motor
- Some of the bolts appear that they're supposed to be nut-less, simply catching on the 3d printed plastic. this is a bad design that doesn't work in practice. The places where there's a slot for dropping a nut catcher in perpendicular to the bolt work great, and that design should be replicated for all bolts.

Simple Extruder Holder
- FreeCAD -File:Motor interface.fcstd. I used M4 nuts for the nut catcher, but for the screws I used added the https://www.mcmaster.com/#90116a217/=14gcc4s that are already in the universal axis, in order to avoid adding a new item to the BOM
- STL - File:Motor interface.stl
