Do you buy Prusament filament?
Do you buy samples?
Do you have nowhere to put your samples?
Then rejoice the solution is here
Prusament comes on a 3 part spool with 2 sides and a cardboard central tube

if you are careful you can pull the spool apart to give you two sides
If you then print this then you can press it onto one of the sides to give you a smaller sample spool holder
NOTE
The model shown in the pictures has a honeycomb pattern on the side
This is done by switching off the top and bottom layers while turning the perimeters up to 5
UPDATE
I have added version 1.2 which has a bigger chamfer and a hole for the end of the filament
And a Fusion 360 design here https://a360.co/2UE7f4Y

The author marked this model as their own original creation.
