New Spool Holder

I had some 8 mm carbon rods laying around and figured my 3D printer needed an upgrade for the spool holder. The rods are nice and long (50 cm each) and I originally intended them for a quad copter build, but I found rc-helicopter tail-rotors made of aluminum to be a better fit for that project.

Finished contraption.
The whole printer/spool holder assembly is quite high, but it saves space on the table at least. It's this high by design since the y-axis moves back and forth and having a bit of distance between the print head and the spool is good in that case.

For the center rod I used a threaded rod. This makes the centering of the bearings easier and also adds to the stability by allowing us to tighten the hold around the bracket from the vertical rod a bit.

Oh, and it rolls so much better than my last try. The design can be downloaded from Thingiverse.

A semi–perforation is shaped by piercing a hole solely half method via the thickness of the steel. A semi–perf may be be} used as a rivet or to locate different elements throughout assembly. Metal is drawn to a shallow best plus size thigh high stockings depth to offer pads for bolt heads or bearing surfaces. Note that the corners of this shallow draw may have almost sharp corners if desired. After importing your half design, you may receive an internet quote that includes manufacturing evaluation to assist improve half manufacturability.
