Reusable spool for Bambu Lab refill

I designed this spool for Bambulab refills, complete with 8 attachment points (there's a 45° angle from one attachment point to the next).
On the inside of the label, I drew a scale indicating the amount of filament remaining.
There are only a few supports to remove, and I had no difficulty removing them.
If the supports are removed carefully, the spool will assemble correctly.
The direction of rotation for locking is indicated on the inside edge.
Locking the spool requires a fair amount of force during the first few uses.
Removing the spool requires more force than installing it (this is to ensure the spool doesn't come apart easily).
I think I did a great job, but above all, this spool comes complete with everything needed for complete use without the need for additional accessories.
The print time was 6 hours 22 minutes (excellent for a spool of this quality).
I used 200 grams of PLA (with less material, the ends would have flared out, and the filament would have risked getting stuck).
Have fun!
