I've printed other spool holders BUT! I've had issues with them being strong enough. After a night of dozens of rolls crashing to the floor after a fateful cascade failure, I learned that the other models I had found weren't strong enough.
At first I just strengthened their models and printed even more brackets but then I realized that was silly. This wastes filament and the more brackets you use, the more they get in the way.
So I made my own. Maybe you can enjoy them too. Here are the details:
A single pair of brackets can easily hold 12+ kg (probably a lot more, I just haven't tested)
Fits a 1 inch dowel or rod (can also use smaller if you like)
Fun little “3D” accent text
Each bracket does take more filament than some other models BUT you need less of them and they won't fall down so easily. In the end you actually waste less filament.
3 screw holes, 2 at the top for strength and 1 at the bottom for alignment.
The support/width of the brackets go right up to the screws, no screw hole extensions. This gives the model much more strength at one of its 2 weakest points.
All holes are properly sized and countersunk to fit drywall screws beautifully.
They are a little shorter than the previous model I used - helps with strength and makes it so there is less height variance when using boxes or just spools.
PLA is perfectly acceptable. Although if you used a stronger filament, these could hold an amazing amount I'm sure.
Warning:
Holders must be properly secured into a wood stud or other sturdy material
As long as you don't overtighten, they won't split and will look great.
So you don't make the same mistake I did:
Here is an example of the aftermath of a different spool holder breaking off the wall.
Example of a different model splitting because the screw holes weren't wide enough, not supported enough, and not properly countersunk.
