Unlockable loose Filament Spool

Who doesn't know this problem: Tons of loose filament samples. Without spool, they are tangled up, and you certainly don't (want to) have a spool for each sample. For changing a sample it's needed to un-wind and re-wind the filament ... :-(

With this 3d-printable spool, it's possible to unlock the spool and simply remove the sample.

The spool is fully 3d-printable, and it's simple to assemble (without need of additional screws) - it just snaps together. Even its diameter is adjustable.

Hints for handling loose Filament:

• Always rotate the spool when winding or unwinding the filament (no twist)
• Fix some tape as a label at the END of the filament, note relevant print-settings
• Keep start of filament away from spool, avoid tangling or over-crossing filament
• Use filament cleaning sponge for printing, loose filament quickly collects dust
