DaVinci XYZ refillable cartridge

thingiverse

Changing filament in a DaVinci cartridge is remarkably easy - simply open up the compartment, disengage all the tiny plastic levers, and then pry free the two small plastic tubes located on either side. Once you've completed this straightforward process, just pop those freshly printed replacement parts into their designated slots to keep everything securely locked together. It's really as simple as that. And since XYZ is transitioning towards selling separate spools rather than complete carts, opting for individual spool refills can be a very cost-effective way of maintaining your 3D printing operations.
