    This is a modification of SP3D's modification of Takei Naodar's feeder.

    My modifications are as follows:
    - Opened up hole around drive gear to allow an MK8 geear to fit without grinding against the feeder.
    - Removed the indicator
    - Added a larger 'window' where the indicator was.
    - Added a bolt to the bearing holder. This allows me to push the bearing back, away from the gear and tighten it in the open position, making it much more convenient to push filament through. 

    Refer to the attached image for reference. Assembly should be self fairly self explanatory.

    Materials and methods

    Thanks. Depending on your spring, it can be pretty hard to push. I ended up printing a thumb screw nut to make it a little bit easier.

    That bolt is a good idea!
