I was looking for a good way to hold several samples at once from the Makerbox Sample Kit. Lots of good ideas out there from fellow Makers. I wanted to put my own filament spin on things and came up with this model.

The is a Main Reel which is threaded. It comes in two sizes, the larger one holds up to 4 of the Filament Reels, the shorter Main Reel holds up to 2. The Filament reels slide over the thread and are held in place with the Nut. When not using one of the sample filaments, simply feed the filament through one of many holds in the reel.
