E3D Bowden Makerbot Replicator 2X Conversion Bracket

thingiverse

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): Print parts. Disassemble Makerbot hot end (remove B wires, keep A). Assemble Bowden hot end (use the Makerbot thermocouple). Assemble EZStruder kit. Drill 2 holes in the back of the printer (I just eye-balled them...). Unscrew 2 diagonal stepper motor bolts (you could use all 4, if so drill 4 holes). Insert the 35mm bolts with washers into the stepper motor on the back. 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.
