eSun Cardboard Spool Centre
Description
[If you find my designs useful, please consider sending a tip](https://www.paypal.com/paypalme/slegnor/1) Remix of my CopyMaster spool Centre to fit eSun carboard spools. eSun filament on cardboard spools have hollow centres. This means, for those of us with bearing-based filament holders, there's nothing inside the spool to rest on the bearings. The filament is always under tension and being pulled off the roll rather than unwound. This simple insert means your eSun spools will rotate freely again without tension on the filament. UPDATE: Added a 84mm version as I found sometimes the spool can work its way off the end of the tube as there's only a few mm sticking out. (I am not affiliated with eSun, I just use their PLA) Print Settings: Quality: 0.2 Infill: 20% Brim: Yes (Personal Preference) Supports: No Material: PLA
