MMU2 Buffer

thingiverse

This buffer, designed with simplicity in mind, makes printing a breeze. To load filament, raise the flexure and then tip the cartridge upwards, ejecting it from its holder. Insert the filament into the exposed Teflon tube located on the outside of the cartridge. Pull the filament through towards the wheel, guiding it into the hole at the bottom (keyed end) of the cartridge. Push the filament through the hole, in through the fitting and down the tube towards the MMU. Replace the cartridge in the buffer. If needed, you can quickly disconnect the Teflon tube to adjust the filament's path into the MMU. Rev B 23 Jan 2020: The text document has been updated to correct errors in panel sizes for the 3" buffer.
