Often times my new spool of filaments was winding around the spool holder on my K1
I saw a model on the USB that came with the printer which was named as " prevent filament entwine "
I liked the idea but it required lots of support and print time was long
So I designed something which won't need any support
Note: This should be compatible with many machines beside K1
Min Spool Holder Lenght:80mm
Spool Holder Diameter: 30mm
Max Spool Diameter: 245MM
Max Spool Thickness: 69mm
Update [31/03/2023]: I have uploaded one more file which is basically same thing but without logo
The user re-uploaded this model. The user is not the original author of the model.
