Spools which split in two, for coils of filament

A few months ago, I bought a coil of filament from Lulzbot that came in a coil, w/o a spool. At the time, I figured I’d reuse one of my empty spools and save some money. Well, watching me try to add filament onto the spool is very comical…

I came across the “Octospool” design (at https://forum.lulzbot.com/t/custom-filament-reel/1048/1) which looks promising. I tried printing it twice but ran into some issues. I’m still tweaking it, but dawned on me that it’s going to take a lot of plastic to print two of them, and when the cost of the plastic needed to print is factored in, it might be more cost effective to buy a spool that splits in two.

Does something like this exist? Where can I purchase one? (molded plastic, not from a printing service like Shapeways)



You could also try the skyhook method here.


Nice! I’ll give the skyhook a try. Thanks!


For what it’s worth, when you buy eSun filament packaged by eSun, the spools are made of two halves held together by two nuts and bolts. The two halves aren’t glued together – just unscrew and separate. You have to get the stuff boxed directly by eSun though – the eSun I’ve gotten through Lulzbot comes on a solid spool as far as I can tell (). Amazon sells the stuff eSun packages itself for around $25/spool. If you look at the third picture here, you can zoom in on the spool and see the nuts: http://www.amazon.com/filament-1-75mm-Makerbot-Printers-Semi-transparent/dp/B00PRY1792/

) It’s all HIPS, and I’m allergic to it, so I haven’t gotten to the end of the spools to know if they can be separated easily – it doesn’t look like it with spools full of filament.

I’ve got a bunch of the empty eSUN spools. If you pay shipping, I’d be happy to send you one or however many you’d like. Send a PM if interested.

Have you considered LulzBot’s spool for loose filament: https://www.lulzbot.com/products/plastic-filament-spool

It’s out of stock, but like everything LulzBot, you can print your own: http://www.thingiverse.com/thing:22759
