If you love Jessie filament as much as I do, you’ve probably noticed a small challenge with its spools: the slight indent in the plastic causes them to shift left on spool holders in enclosed setups. For Prusa printers, this drift can lead to accidental collisions with the extruder, especially on models like the MK4S with its modified fan.
The Solution:
The Jessie Filament Spool Extender is designed specifically for Jessie spools to keep them securely aligned and prevent drifting. This extender ensures smooth operation with any Prusa printer in an enclosure and is especially useful for MK4 and MK4S models.
Why It’s Great:
- Fits snugly into Jessie spools to prevent unwanted movement.
- Perfect for all Prusa printers in enclosures, particularly the MK4 and MK4S.
- Quick to print, simple to install, and reusable—just pop it out of one spool and into the next!
How It Works:
When combined with the spool-holder-2-8mm.stl file from the Filaments and Prusa Buffer MMU3 project, it creates a reliable, collision-free filament setup.
