Welcome to the world of filament samples. If you happen to be using 2.85, then read no further. All you need to do is take off the zip ties. If you're using 1.75mm, you may want some tips to prevent turning your nice sample into a rat's nest.
First, find something to put your sample on. An empty spool laying around works just fine or you can be a bit fancier and print a spool holder. We have some ideas in this thingiverse collection.
If you're using a printable holder, you can probably just put the sample on the holder, remove twist ties and go.
If you're being cheap like me, you're probably just using an old empty spool. When I do this, I will remove the zip ties and then carefully, loop by loop, wrap it on to the spool. If you hit a tangle, then usually the easiest solution is to walk the tangle through the loose part of the sample. Remember, there are only about 40 loops on these samples, so walking a tangle out may be easier than you think.
