Mini (500g) Bambu Lab Reusable Spool Holder - for refill filament bundles

I just took delivery of some 500g refill rolls of Sunlu PETG so needed a reuseable spool to put it on, found a 250g remix of this one, but not a 500g one so remixed this model. When printing I'd suggest you make the bits that clip it together solid when printing for strength, simply add a modifier in Orca Slicer, choose a cylinder and resize it to fit over the top 10% of the print (where the 4 L shaped tags are on each part) you will only need a few layers of solid, you don't acyually need it but it doesn't hurt to add it now to make those tabs stronger. Minimum I'd use is PLA+ - I used that and it's fine.
