Kossel Clear Top PVC Spool Holder Brackets

thingiverse

These two brackets will hold a 1/2" piece of PVC tubing, suspending your filament spool above your Kossel printer. I designed this for a Kossel Clear, but it should work for any similar sized Kossel printer. A single M3x10 screw and nut secures each bracket to the 15x15 aluminum extrusions at the top of the printer. On the bottom of the bracket are small "buttons", which keep them from twisting by locking them into the extrusions. By using these brackets, I was able to suspend my Mk8 extruder from some 1/2"x1/16" aluminum L-channel so that it hangs between the spool and the effector, shortening the path between them. Instructions I printed them exactly as they are here -- laying on their sides. No support structures were required. I think I used 25% infill, but they don't need to be very strong, so would expect 20% or even 15% would be okay. In my setup, the PVC tube was 315mm long, but you'll probably want to adjust this for yours.
