Introduction: PVC 3D Printer Filament Bobbin Holder - Version 1.0

About: Welcome to my Instructables channel where I'll share my wacky and unique creations that hopefully others find useful, or better yet, inspire an evolution of even better ideas!

CAUTION: I stopped using this holder in favor of Version 2.0. Please refer to that one here.

  • I found some filaments are not wound very well and the added tension from poor winding and the friction from this design of holder was causing problems with my printer's extruder.
  • Overture Brand are wound well
  • PRUSA filament (at least the clear 1.75mm PLA) are not wound well

If you still want to make this, please continue, but be cautious of your extruder. (Clicking noises are a bad sign.):

NOTE: This is sized for a 65mm wide bobbin.

Cut two pieces of Schedule 40, 1-1/2" PVC pipe to 6-5/8". (1-5/16" of this length is inserted into each side of the elbow fitting.)
Cut two pieces of Schedule 40, 1-1/2" PVC pipe to 2-5/8". (1-5/16" of this length is inserted into each side of the elbow fitting.)

See the second image above for the spacing. 4" on the long side, and 1" on the short side. If you cut each piece of pipe the proper size and fully insert into the fittings you will end up with these dimensions.

You can glue the joints or just leave them dry fit. I chose to just leave them dry fit.

    So with this design, you have four points of contact causing friction between the holder and the spool?

    lime3D,

    You are correct. However they are 4 very small points of contact compared to the one large one for the traditional bobbin holder setup. And the smooth plastic of the bobbin rubbing on those very small and equally smooth points of contact is actually less friction than using the holder that came with my printer (Ender 5 Pro). The Ender's holder was actually very rough compared to the plastic on these irrigation elbows.

    I also did a pull test comparing the two and this setup was noticeably better. (This was just by feel, but again you could really tell the difference.) In reality, all printers' extruder motors have plenty of force to overcome this small amount of friction, so in the end either method is fine, but for me cheap and functional always wins.

    Thanks for the great question. And if you get a chance, review the Instructable again, I added a new configuration that works much better.

    Very nice. I swear we need an Engineers Day.

    Thanks. Its much smoother than the standard arm style that holds the inner diameter of the bobbin. These irrigation fittings are really smooth and the outer diameter of the bobbin glides really nicely on them.
