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
