Recommendations Please: Best Extruder For E3D Hot-End

I have in my possession on of these bad boys: A 1.75mm E3D All-Metal Hot-End



I am trying to decide how to best implement this in a Prusa-esque build. The E3D Boys apparently drop this into the version of the Wades Extruder that Nophead bundled with the Mendel90. It looks like two m3 bolts are what holds it in place.

I would like to hear your thoughts. What extruder you think would best suit this hot-end in a Prusa-Style build?

Please keep in mind that this extruder is made for 1.7mm filament. Would you recomend a specific type of hobbed bolt? Any special ideas for mounting it?

Thanks for your thoughts

Personally, I have only ever used the RRP style (6mm hobbed bolt) extruders with 1.7mm filament.

I have never used a carriage mounted extruder to push 1.7mm filament. I have never seen 8mm hobbed bolts that have a groove cut into them for purely for 1.7mm.

I have one of those. I printed a new ABS piece (the red one in the pictures) to make it groove-mount compatible. I'd be happy to share the file for it if you'd like. I use a PG35L geared stepper extruder with it, but a standard Wade's should work just fine. I would recommend printing one with a smaller filament hole diameter though since the 1.7mm filament is more likely to buckle in a 3.5mm diameter hole. As long as the hobbing isn't too deep, a standard hobbed bolt should work just fine as well.

Awesome Cameron,

Thanks so much for your insights on the matter. I would love to check out your custom printed piece. Can I find it online or should I PM you my email address?

I have attached the file here. If you have any questions please let me know!

I unfortunately didn't realize that the hotend would only be compatible with 1.7mm filament before I bought it, so I have only been able to use it with polycarbonate since all my other plastic is 3mm.
