Counting matching models…
I had an unfortunate mishap with the genuine mastercore reusable spool solution where the cardboard side came off. Filament everywhere and became knotted. This design should stop that. Design should be self explanatory. notes : 4mm reel…
Intended as an alternative to the original clip-in core for the 3DTomorrow MasterCore system - see: https://3dtomorrow.com/product/mastercore-uk-pla/ - which I tried, but in my case found that it didn't hold the spool faces on tightly…
I needed a project to learn tinkercad and had refill filament packs from Esun, Sunlu and 3D Tomorrow so I started this project. This one fits the Mastercore refills and just fits the Sunlu too, I will work on the others and add to this.
