Unlockable loose Filament Spool
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
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
