Mouth Cable Bobbin for Assistive Technology Challenge

We probably all have seen cable bobbins, but they are not very easy to use with one hand only. I hope this design can help a bit in this matter.

Posiblemente todos hemos visto enrollacables, pero no son muy fáciles de usar con una mano. Espero que este diseño ayude un poco.
