I have been developing a prototype for an improvement to the way we dispense Nylon from a large spool. Our current approach uses a hub and axle. If a strand of Nylon filament comes off the spool, as it is prone to do, the print will be ruined when the Nylon gets tangled around the axle. The new approach uses rollers to support the spool. It does not prevent Nylon from coming off the spool but it self-clears every time with no negative impact on printing. This entire assembly fits inside of a dry-box which prevents the Nylon from being degraded by moisture.
