Fisher pneumatic upgrade

Description

This small kit of parts can be used to upgrade the Fisher Delta machine’s filament feed to make it easier to disconnect the bowden tube from either the head or the extruder drive. As well as the new hardware, a couple of printed parts have been redesigned to fit the new components. The new effector design has the fan repositioned to allow extra room for the pneumatic fitting, and the extruder drive block no longer requires a printed tongue to secure the bowden  tube. Instead, the pneumatic fitting screws directly into the internally threaded hole in the side of the drive block.

The kit includes:

2 x Pneumatic fittings

1 x Heatsink (with M6 thread to receive the pneumatic fitting)

(Optional) Printed drive block and effector.
