Hi there,
I've made this spool extender to solve a problem where the original spool holder was in the way. Please note that the strength of this model may vary depending on the use case. I've tested it with a new 1kg spool, and it works just fine. If you have any problems, please contact me.

Hardware:

• 2× the original spool screws + nuts
• 1× M3×12 screw, 3 washers, and a nut for spacing (not necessary if you have one that fits just fine)
• 1× M3×8 screw

Happy printing! :)
