Summary

Pending Update!!!

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!

Original Text:
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.)

Print Settings

Printer:

CTC-3D Dual Extruder (Bizer)

Rafts:

No

Supports:

No

Resolution:

0.25mm or larger

Infill:

15% or more. Triangle pattern recommended.


Notes:

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 I Designed 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!

NOTE: I replaced the version 3 files with version 4, which has a feature I thought was unnecessary-- an additional 1mm lip --and removed from my original design. (Without it, spools with very thin rims might be able to come off the bearing.) This version is now identical to the ones I've been using with my printer for almost six months now, and as it turns out the difference in print times was entirely negligible anyway.

Instructions

For one complete spool holder you need to print two sets of parts, and you will need four common 608 bearings.

  1. Print two each of PartA and PartB.

  2. Press-fit 608 bearings onto bosses on PartA. (Should be a tight fit.)

  3. Press-fit PartA and bearings to PartB. (Should also be a tight fit, might not get them apart again.)

  4. ???

  5. MAKE COOL THINGS!

I printed these in PLA. A 'tight fit' is a bit of an understatement. I could simply not get the bearings to fit =/

I'm sorry to hear it gave you some trouble. If you don't mind, what slicer did you use and what were the settings for number of perimeters? (I see you already listed layer height and infill in your Make) Because this certainly doesn't seem to be typical of the results people have been getting, and it'd be good to nail down the cause.

Looks like one more reason for me to offer an alternate version held together with a nut and bolt, when I do the redesign, as the variances from printer to printer make the tight tolerances for press-fitting less than idea... (I've been sidetracked with some really cool projects, and haven't had a chance to get to it yet!)

I really like the blueprint, do you mind share how you created that image? :D

Sure thing! :) I export the drawings from Autodesk Inventor as a PDF, open it in Adobe Illustrator, modified and rearranged the elements of the drawings the way I wanted them, and then paste the vectors into Photoshop and create the final image.

You should be able to follow the same workflow with Fusion 360, and any vector drawing app that can open PDF files. (The Photoshop step isn't really necessary unless you get really fancy with it.)

Speaking of 'really fancy', since then I've gotten into using a 'retro pack' of grunge and damage brushes that I bought on Sellfy to 'age' my blueprint pics. :D http://media.makecoolthings.com/wp/2016/02/pendant_blueprint.jpg

Wow, fast answer and thank you for sharing! That age/worn/distress effect on the pendant blueprint is awesome.

This works great!

Thanks! I've got some more useful stuff in the works. ;D

Will try those!
I just ordered 10 bearings (608) for under 5$ delivered: http://www.aliexpress.com/item/High-Quality-10PCS-ABEC-7-Deep-groove-ball-bearing-608ZZ-8X22X7-mm-bearing-steel-608-ZZ/32442674267.html
They may be not sooo high quality, but for the low stress in this application surely more than enough...

I'm sure they'll be more than sufficient! :D I chose the 608 bearing because they're the common 'skate bearing' you can get pretty much anywhere for cheap. Enjoy! :)

Nice looking design. very clean and looks well thought out.

What did you use to create the blueprint picture? Was it through whichever CAD program you used (if so, which program)?

Thanks. :D

The lineart and parts list are from an Autodesk Inventor drawing; I exported it as a PDF, and that allowed me to import it into Photoshop as vector graphics. (The first image is a screenshot of the assembly in Inventor)

Great work. (would love to see mod for wall mount and dual flanged bearings as mentioned on reddit)

Best of luck!!!!
