E3D Bowden Makerbot Replicator 2X Conversion Bracket

I haven't been using my Replicator 2X for a while now, mainly because it doesn't extrude well...or at all most times. I decided to swap over to a Bowden style extruder.

I originally followed the guide here. The guide gave a link to some 3d printed parts, they were all undersize for me and I didn't like the way the hot end was being secured...so I made my own.

Note: I never really use the dual extruder setup, so this bracket only supports one extruder.

Bowden Parts:

• 24V 1.75mm Bowden Hot End Kit
• EZStruder Cold End Kit

IMPORTANT: On the EZStruder Cold End Kit, you need to check the 4mm Quick Connect Fitting!!! I forgot to do this...

Other Parts (I used 4-40 instead of M3...but they're essentially the same size):

• 4 - M3 x 18mm Bolts (Hot end)
• 2 - M3 Nuts (Hot end)
• 2 - M3 Lock Nuts (Hot end - I didn't use these...you should...)
• 1 - 1/4 x 4in Aluminum Rod (Hot end)
• 2 - M3 x 35mm Bolts (Cold end - You could use all 4 of the stepper holes...I did not)
• 2 - M3 Washers (Cold end - You could use all 4 of the stepper holes...I did not)

Instructions (I followed the original guide for the majority of this...but in summary):

1. Print parts.
2. Disassemble Makerbot hot end (remove B wires, keep A).
3. Assemble Bowden hot end (use the Makerbot thermocouple).
4. Assemble EZStruder kit.
5. Drill 2 holes in the back of the printer (I just eye-balled them...).
6. Unscrew 2 diagonal stepper motor bolts (you could use all 4, if so drill 4 holes).
7. Insert the 35mm bolts with washers into the stepper motor on the back.
8. Load, level, and print (be sure to move your bed down a bit to make sure you don't gouge it!).

Finishing Note: On the first hot end picture, you will see 2 black bolts where the limit switch foot is. I lowered the head a bit, and failed to compensate for the lowering of the foot...thus the limit switch wasn't hit by it. This is fixed in the uploaded design, AND YOU DO NOT NEED THEM.
