BQ Prusa i3 E3D Bowden

Hey all!

Had a BQ Prusa i3 laying around that never worked with the Witbox extruder. So I decided to modify something to make a Bowden setup.

You can use any extruder, but the one I included is just a mod of the Thingybot extruder. It uses a MK7 drive gear and 608 bearing.

To install the E3D -

Attach the body to the X carriage using two M3 20mm screws.

Place the E3D hot end in the mount

Put the top cover with 40mm fan mount on and screw it into the extruder body using two M3 16mm screws.

Attach the 30mm hot end fan on the side

Attach the 40mm part cooling fan on the front

For the extruder -

Using 3x M3 8mm screws attach the extruder body to the stepper motor

Align the MK7 drive gear to the filament hole

Attach the Bowden push fit connector

Take the idler, put the 608 bearing on it, then add the cap with a M3 12mm screw

Attach the idler to the extruder using a M3 16mm screw

Put a M3 nut into the hole by the filament inlet

Put a M3 16mm
