One Piece Spool Holder

This looks like a giant pizza tripod.

I just printed this and it works great! It's so nice to have a spool holder that isn't a puzzle to use. Thanks for posting!

Ive just finished printing this, and its excellent!

Earlier this week, I had a bad experience with another (uber) one piece spool holder, which could not hold the weight of the spool without bending and twisting. Fresh with that disappointment, I saw your design appear, and saw that it answered all the shortcomings of that other design.

Fresh off the printer, its solidly holding a full spool. I can confirm that your design uses half the filament and prints in half the time of other singe print, one sided designs available at the moment that I looked at.

I printed in PLA at 0.3mm with 3 layers top and bottom, 3 perimeters and 15% infil. Cura estimated it would take 4 hr 52 min, but of course it took a little longer - more like 5.5 hours. and only used 82g of filament.

Thanks for sharing the design, I'll see about getting a 'make' photo up when I have the opportunity to take a photo in daylight.

Yeah, the only other two I'm aware of, besides one or two I've seen and admired in YouTube videos but never found files for, are "Uber Spool Holder" and https://www.thingiverse.com/thing:2036761. I admit I didn't actually slice Uber, but looking at the pictures it seemed like it'd take too long and be too weak - guess that was a good bet. And "One Piece" I liked (enough to use its basic structure here), but no matter how I sliced it it came out to >10h which seemed too much, and I thought it could probably be a little more aerodynamic :). So far, this design printed in PLA doesn't sag appreciably even with a full 1kg spool, and I imagine would be fine with an even heaver one. But if not, you can always scale up "spoke diameter" in Fusion360 for added rigidity.

Thanks for the comment, I really appreciate that you're enjoying it!

How do you redirect the filament at the top of the printer?

Ahhh fair question!

In the first picture, you can see the box around the printer. I haven't posted it, because it's pretty well a work in progress, but it's a full enclosure made of 3D printed frame parts and coroplast from Home Depot. The spool actually sits on top of this, and feeds filament through a small hole right above the middle of the print bed range.

I imagine for most other people who need a standalone spool holder, they've either got a similar setup, perhaps with the spool sitting on top of a LACK table for those kind of enclosures, or else have a reverse bowden type of setup or something.
