UPDATE 24/oct-2024:

This model is succeeded by my new set of dividers, they are completely reengineered  from scratch and has many new features, most notably is no more threads. The halves snap together now, making everything much easier to print. Check them out, they come in 3 sizes:
⅓ spool (holds about 250g) - [https://makerworld.com/en/models/727503](https://makerworld.com/en/models/727503)
½ spool (holds about 400g) - [https://makerworld.com/en/models/727526](https://makerworld.com/en/models/727526)
⅔ spool (holds about 550g) - [https://makerworld.com/en/models/727544](https://makerworld.com/en/models/727544)

Modular subdivider for Bambu Lab-filament spools

This filament spool subdivider drops into Bambu Lab-spools to allow storage of three different types of filament in one spool. This is an efficient and useful way to store leftovers or samples of filament of up to about 250g.

This remix is reverse engineered and redrawn from scratch from @giuliolibrando's Bambu Lab Modular Multi Filament Spool. 
The most important features of this remix are:

• Fixation holes in the rim of the spool, allowing filament to be fixated without using a filament clip/stopper.
• An angled insertion/attachment hole for fixing the filament when winding up filament, allowing for crusty and brittle filament to be wound without the end snapping off. This also holds the filament better, as with the normal hole, there is nowhere for the filament to go.
• A slightly larger spool diameter, fitting better with the edge of the bambu-spool (allowing for slightly more filament).
• Inclusion of the raw model-file (in Fusion360-format) with easy-to-edit parameters.
• Fixed the locking-tab not being centered, causing wierd-looking-ness, if the subdividers are not oriented the same.

Assembly

The two halves of a subdivider screws together and is slid onto an empty Bambu Lab spool (without the cardboard part).

Please see the original model for very cool assembly instructions HERE.

The remixed model is compatible side by side with the original model, but they can not be screwed together with the original halves.

If the threads are too tight or too loose, you can try adjusting the thread_clearance in steps of 0,010 - 0,005mm.

The halves might need to be screwed forwards and backwards a few times in order to run easily.

Print Settings:

The subdividers in the images are printed without support from 'Dutch Filament (MCPP) Light Grey ASA-X' at 0.23mm layer height with a 0.4mm nozzle on a Bambu Lab X1C. In order to improve the quality of the threads, the model is printed with variable layer height set to 0.25 (Quality / Speed-slider)
