Help keeping Spools neat

Hey All,

I have a question. I have have my spool mounted on this holder…

Spool Holder by Danimal_3D

Tired of buying proprietary printer spools/ cartridges? Print off this spool holder. I used hot glue to stick it down to the top of the Da Vinci XYZ printer.

For the first 25% of the new spool the filament always gets tangled and wrapped the spool and is a big mess… Dose any one have any reccomindations to keep new spools in check?

Hey Nicholas. The problem usually occurs because the filament was originally extruded onto a larger diameter drum before being transferred onto smaller spools. Therefore the “natural” curvature of the filament is larger than the spool and that’s why the filament “springs” off the spool. This acts rather like a watch spring and, if the tension is sufficiently strong, the filament can act to unwind the spool. What you need to do is somehow increase the friction that prevents the spool from rotating backwards - Just a little. It may also help to run the filament through a small piece of sponge between the spool and the extruder. This also makes sure that the filament is dust free before it gets into the extruder. If you intend to use this spool holder, I’d suggest that you try putting a pencil through the holes in the sides of the spool holder which should prevent the filament from moving outside the diameter of the spool and might also cause enough drag on the spool. I’ve found that a spool holder that has some rotating bearings at the bottom on-which the rim of the spool sits, works very well because it keeps the filament within the spool rim. Hope this helps. If I haven’t made sense to you, let me know.

Cheers!

Hey Nicholas, you might want to give this 3D printable spool a try, it’s pretty awesome: Talk Manufacturing | Hubs

What dose everyone think of this? I want to build a one way filament valve using a razorblade. This would act as a zip tie only allowing filiment to go one direction and the blade would dig just a little if it the printer pushed at all. The problem with my printer is that the filiment feeds in from the back not from the top. So when the print head moves foward and back it back feeds to the spool making. It tangle.

That looks awesome. But I feel I would still have the same issue due to how my printer takes in filiment. It’s rear loaded and not top loaded.

I made it a filiment one way guide. Will be on thingiverse soon
