Spinning String (or Earbud cord) Wrap

I have several labs that require eight 2m long ~1/16" (2mm) strings. These strings are a pain to keep organised and regularly became a tangled mess in their box. Well no more!

I originally found this thing:967001 by DesignSpark which I really like but it was too small and I found the sharp edges of the "handle" kept scratching my finger and thumb as I unwound the string so I redesigned my own.

My version has beveled edges to give better bed adhesion without support, a larger handle so I can more easily hold it while unraveling the string, I also changed the angles of the split so that it doesn't need support in that area. I added a hole in the handle to enable me to hang them on a nail or a loop or large wire keyring.

They now work perfectly for my application which is storing a length of ~1/16" (2mm) string.

It is super fast to unwind the strings and winding them up is much faster than winding them on three fingers and then tying a knot.

Thanks DesignSpark for the inspiration.

The part prints well for me with no support.

Printer settings

I sliced with Cura and printed them on an Artillery Sidewinder X1 with the following settings and material:

• PLA (I used black from Tinkerine)
• 0.2mm layer height.
• 10% gyroid infill.
• 2 shells.
• Extruder temperature 210 degrees C.
• Build plate temperature 55 degree C.
• No support.
• Brim on.

Assembly

• Clean off the brims and any support and then spin it a few times to make sure the winding pin is clean. Mine come of the printer pretty loose.
