Mini Master Spool Spacer for Filament Samples

I quickly found it difficult to use the mini master spool with filament samples. I like the ease of the quick change system, so I created a spacer that allows you to use the roll with filament samples. You just take the tail of the filament and seat it in the spacer, and then place the sample over the post like normal. The head of the filament can then be secured to the mini master spool when not in use.
