Top platform

During the "loading/unloading" filament procedure I find it a bit hard and uncomfortable to pinch the feeder's arm up. And if I need to pinch for a longer time it can become painfull for the fingers. So I designed  a "Top platform" part that can clip on the original feeder to offer a more comfortable thumb placement. It allows for a painless and increased pinch force.

Fine tuning add-on

I then designed a filament griping force fine tuning add-on. It's made of two main parts :

  • a tuning screw fixed at the tip of the feeder's arm
  • a fine tuning knob placed on top of the "Top platform" printed part

I later added a third part that allow to easily lock the feeder's arm in the upper position (ungrip position). This is very usefull when you wish to keep the filament ungripped for a longer time. I use it every time I need to perform a filament load.

Arm front access

This last part gives a front access to the feeder's arm mechanism that can then be triggered by pushing it backward.
