Spool winder with joiner and tensioner

A remix of the wonderful model by Les Kaye.  Added a connection piece in the middle that allows for a movable tensioner or static filament guide.

Print the big pieces however, but make sure you print the joiner bobbin, carriage rod, and carriage at 100%.

Carriage requires 4x M3x15 screws, carriage rod requires M2.5xWhatever to hold the carriage rod in place.

Joiner takes 4x M5 nuts and bolts to keep it all together.

All holes in the carriage and bobbin are small by design, drill them out to what you'd like to.  The carriage rod is a bit thick on purpose, sand it down so it slides freely. I put it in a drill and spun it on sandpaper.

Check the original spool winder for all other relevant info.

There's also a spool adapter that is specifically designed to fit into the Bambu reusable spools. 

Go forth and enjoy :)
