This is a reel for the nylon filament.
Or, any kind of filament you want to use!
I ordered some nylon filament and it did not come with a spool.
So, I made my own.
This spool will require you to use the filament holder from octave.com.
It is a free download.
You could find some octave filament holders on this site, too!
I believe, now though, they are shipping the nylon on spools!
I am using it on my Afinia 3D printer.
Print 2 sides.
Print the center spool.
I printed in ABS.
Glue together with some ABS cement.
(you can get from your local home store.)
Make sure the flat sides of the sides is towards the center.
Next, I have to make a winder....
My arm is sore!
