Simplified Spool
Build-in-Design Number 11

Update: 2025.08.03 

At first: Thank you chiz for your work.
I have made a new, simple Design, based on your Work.

You can used if you copy the File spool_style_11.3mf to the other
spool_style_??.3mf-Files.
In File Customizable AMS Spool Generator v1.01.scad you need some Changes:

module assemble_spool(Style_Number=1, rotns=3, Spool_Part_to_Generate, Label_Text) {

   dflt_rotns = [  
       0, 12, 12, 12, 0,
       0, 0, 6,  0, 0, 0 // Add ", 0"
   ];

   style_files = [
       "spool_style_1.3mf",
       "spool_style_2.3mf",
       "spool_style_3.3mf",
       "spool_style_4.3mf",
       "spool_style_5.3mf",
       "spool_style_6.3mf",
       "spool_style_7.3mf",
       "spool_style_8.3mf",
       "spool_style_9.3mf",
       "spool_style_10.3mf",
       "spool_style_11.3mf" //Add the new style
   ];

This are all Changes for the Original File.

But there is a 2nd File: Customizable_AMS_Spool_Generator_v1.01_remix.scad.

There are some more Changes included:
A new Parameter for the Label: Label_Text_Size = 10;
Changing spacing and d for the Rounding Text
Changing the Label (See the Foto and Screenshots)
Add the Label to the "Narrow Part" too
The Font is now 0,8mm engraved (see Screenshots)
And this Font is "Chinacat" from [https://www.dafont.com/chinacat.font](https://www.dafont.com/chinacat.font)

All other Files are from the Original.
The spool_style_11.3mf are made with "FreeCAD", export with FreeCAD to 3mf.
The FreeCAD-File is included.

Update:
Add a Place for a Label (here 60x40 mm)

Update: 2026.07.14
Attention: Use OpenSCAD 2021.01, not the Nightly Build!
My 1st Test with Nightly Build was ca. 2,5mm to small.

Add spool_style_12.3mf, same as spool_style_11.3mf, but 8mm wide.
FreeCAD(1.1.1)-File included.
You could change the "Wide" in VarSet, here 8mm.
Only testet with 6mm and 8mm.

Changed the Letter-Deep from 1.1mm to 0.6mm, see Menue in Openscad

Made with:
PrusaSlicer 2.9.6
FreeCAD 1.1.1
OpenSCAD 2021.01

Filament: PETG
Layer: 0.2mm
Nozzle: 0.4mm
Support: No

Example: See the last 3 Pictures in the Gallery, here are the Spool labeled with my First Name
