2017/07/25: Wow! Sorry I've taken so long and been so quiet (you should see my blog!) but...life happens! I've uploaded the new version of the spool holder that is a single interchangeable piece, so you just print four of them and you're good to go! I put the old version in a zip for safekeeping so Thingiverse wouldn't auto-generate images for those objects anymore. I'll be updating the assembly drawing soon!
Other changes made to the design: Went from inch to metric, so I rounded out the dimensions just a little. And I removed an unnecessary hole that was doing nothing but adding perimeter-printing time.
2017/02/01: I've been meaning to do this for a while, but I've had a lot of projects going on, as part of my return to actively designing for Thingiverse, I'm going to update my first (And very popular!) Thing.
First and foremost, I'm going to remake it in Fusion360, because I'm transitioning over from Inventor. But I'm also going to incorporate the very common sense feature included in dara's remix design; namely, making a single part that can be used as A or B...I don't know how I didn't think of it, I handle lots of items designed like that every day! Don't worry though, that'll be it, it'll be basically identical, just without the need to print two different parts. These are still fantastically simple spool holders, and I still use mine!
This is a spool holder I designed out of necessity back in March, not long after I got my printer. I consider it to be the first 'real' part I made. Print two sets of parts for one complete spool holder. You will need FOUR common 608 bearings, a.k.a. 'skate bearings'.
It uses standard bearings that most Makers probably already have a drawer full of and that makes the spool rotate super-smooth. It's also relatively fast-printing, and you can get away with printing it at as low a resolution as you'd like to make it go faster. (I'd recommend not skimping on infill though.)
It should fit any spool, so long as the flange of the spool isn't thicker than the width of the bearing... And out of 8 different spool types I have, I haven't found one that didn't fit. (Even a mini spool wasn't small enough to bottom-out between the bearings.)
CTC-3D Dual Extruder (Bizer)
15% or more. Triangle or hexagon/fast-hexagon pattern recommended.
IMPORTANT: If your printer doesn't print dimensionally-accurate parts, you're going to have a bad time. The bosses are 8mm OD, to match the ID of a 608 bearing, and the mating holes are 7.9mm ID... So if your slicer has an 'Horizontal Size Compensation' setting (Simplify3D) this would be the time to use it if you need to...
There aren't any real fine details, so feel free to print this at the biggest layer height your printer and material can handle. I wouldn't recommend going any finer than 0.25mm just because it'll increase print times and all the layer ridges might make it harder to press fit stuff.
Triangle pattern infill is great for truss-like structural parts like this.
How it came about...
I was putting my printer on 14-inch deep wire shelving, but it would only fit without the filament spools mounted on the back. I decided the thing to do would be to mount the spools on the shelf above, and run the filament down to the printer...so I'd need to make spool holders!
For one complete spool holder you need to print and assemble two sets of parts, and you will need four common 608 bearings.
Print four duplicates of the part. (Version 5)
Press-fit 608 bearings onto bosses on each part.
Press-fit the halves together. (Should also be a tight fit, might not get them apart again.)
