Stackable Spool Organizer

3D model description

This build is designed to make use of the empty 3d Prima Select 750 gram spools I had at home. I wanted to make my organizer stackable and unstackable so I designed the part call "Spool Connector A & B". This part allows the spools to stack untop of each other and latch on to each other.

I also wanted different sizes on the compartments so I designed 3.


Each size has grooves to allow dividers in corresponding sizes to be inserted.
The compartments have small knobs that will fit in holes drilled in the spool. This will prevent them from swinging open all the time. (This doesnt mean the design is foolproof and I don't take any responsability for any lost or dropped screws, nuts and what have you).
In order to drill the holes in the right places I've included a "hole pattern". One large for you with large printers and a "1/3 pattern" for you with smaller printers.

Inlcuded are instructions on how to make the holes and assemble this.

In order to make the build, you will need a 4 mm drill bit and optional spare rivets for extra stability.

I've included STEP files to the parts and your free to modify this build as you see fit.

Have fun with it.

3D printing settings

0,16 - 0,24 layer height depending on your choosing.

The prints in the pictures were printed with 0,24 mm layers.

No partiuclar supports needed, in fact avoid using them, otherwise the guide holes in the models can get hard to remove supports from.

The "spool connector" A and B is best printed with PETG to allow them to flex. Theres a chance the snap hooks can snap if you print them with regular PLA.

My name is Erling del Castillo.

Im a 3d printing specialist (hard earned title) who started using CAD software about 10 years ago.
At that time, I was doing CAD because it was fun and in a way I used to make what I consider art.
At that time renderings was the result of the cad work, what I could show to others. 3d printers was heard of, but stil to expensive for non professionals.

About 4 years ago, the printers had dropped in price and it was time to start to take the next step. Now renderings wasnt the only visual media, but now I could also produce physical models and I could interact with them.
I was hooked, this was gonna be my life from that day forward.

I had recently started to get an intrest for cosplay just prior to the 3d printing intrest and to try and combine them two was a given for me.

I started with some 3d printed lightsabers, because I love Star Wars, but I couldn't find it reasonable for me personally to spend 100's of dollars on metal hilts and electronics.

I started posting my creations on and it soon picked up and people really liked my work.
I focus a lot on details and functionality when I design something. Modular design is almost a must, because my creations are meant to be finished by someone else, not me personally.
If I can make that work easier somehow, Im gonna spend extra time and make it so.

So almost all my creations are sectioned, to ease both the printing process and also post printing work, such as sanding, priming and painting.

When "The Last Jedi" came out, things really picked up. I had done the Kylo Ren's iconic crossguard lightsaber replica kit and when I saw the look of Ben Solo's lightsaber, I had it redesigned and printed the day after.

Shortly after that this happened:

and today, with over 125 sold lightsabers and lots lots more printed I've taken the step further.

You will soon find designs to allow YOU to print ligthsabers that can take electronics and actually be more then just shelf decorations.

BUT I'm much more then just a SW replica designer and I intend to post all of my creations here.
AND my creations, you have my blessings to reproduce them (the actual prints, not the STL files) and use them as you want. All I ask in return is that you please mention me as the original creator of the 3d model.

I hope you will like them.
