Our filament-sample spool can be used with small samples of different 3D materials, like our 50g and 100g samples and hold up to 200g in total.

The sample spool is easy to print even on a Prusa MINI with different kind of materials. It was printed with nobufil petg but you can use any other materials, of course. 

Just print the file twice and add a piece of filament to lock it in place. You can use up to 2 sample spools in our box so that can be easily stored.
