Powerspec ultra filament guide receiver

thingiverse

After a few years of use, the filament tubes no longer stay inserted into the retainer on the top of the hotend for my Powerspec Ultra machine. I bought new filament tubes, only to find that the wear was in the plastic piece at the top of the hotend. I modeled this in tinkercad and printed in PLA (that's not hot enough to need ABS, though I might print in ABS if I were doing it again). The holes need a little bit of reaming and I used a 180 grit sandpaper so that they wouldn't be too smooth. Ultimately, it works, pretty well.
