This is an adapter to fit my filament spools onto my 8mm holder's axle...

Inner core of spool from 45mm to 60mm

I created these links where you can find all common filaments and spare parts at the best prices. These are just links to selected eBay and Aliexpress items, where I normally buy spare parts and materials for my printer, prices are excellent and products are good. If you buy something from here you will support me a little bit to make these projects.
