Interlocking Filament Spool - 82mm

First, this is NOT my original design Someone much more creative than I created this! And they did an awesome job. But the original version did not fit ANY of my filament refills. So I dissected the design and made the inner spool 81.5mm to fit the 82mm spools I had. Then i made the center (spindle) hole larger so it would fit my Elegoo printer spool spindles. After that I tried it in my Anycubic ACE (multi-color) unit and it was a bit too thick on the edges so I made the outer band 3.5mm instead of the origina 5mm. Finally, I designed a pop-in/pop-out label holder (so I knew what type of filament was being stored on it). The spool has "SlantSpool" text on the center spindle but it doesn't match any of the SlantSpool designs I have seen. And the parametric interlock design is different. Anyway...if someone knows who the original designer was let me know and I'll give them credit for this.

I recommend printing the label holders in PETG as they need a little bit of flex to pop-in and
