Thanks. I was definitely running on the hot side, but the Monoprice filament doesn't seem to flow well below 227 C, and I wanted to prioritize layer adhesion over bridging.

<p>Yeah, looks like inadequate cooling/printing too hot, but as you say, that is highly material-dependent. I would try re-printing with more aggressive cooling or a filament which can handle lower temperatures. I recommend Gizmo Dorks if you are in the US... it is very low cost and extremely high quality... maybe the best I've used.</p><p><br></p><p>Also, I did reuse the bowden push fit connector. </p>

Also, did you reuse the bit for retaining the bowden tube from the original hotend, or did you use a new part. If so, would you mind giving a part number or specs.

Below is a link to a pic of the inside side of the assembly. Quality doesn't look that great. Biggest issue is the overhang that covers the top of the ubis. The hot end seems to fit well, so I am not sure it is even worth fixing; however, if you have some advice on getting a better result, I would be happy to have it. <div>-</div><div><a target="_blank" rel="nofollow" href="http://i.imgur.com/kTtjr2n.jpg">http://i.imgur.com/kTtjr2n.jpg</a> </div><div>-</div><div>Sliced with Cura and printed on UMO in Monoprice 3 mm white PLA.

Let me know if any other specs would be helpful. </div>

Rotated 90degrees; Solidworks uses a Y up coordinate system for some reason...

What orientation is this meant to be printed in?

Thanks for the .step file!

Hi Nick, Do you have the .STEP files of this design? I tried it with PLA & crossflow and it works great but I'd like to print ABS too and in order to do that I will have to add a fan mount on it.
