This cat ear esque fiber optic loop holder was designed to work with Leviton structured media closets and their pins. It can be oriented in many ways using two pins to fix it in place.
The fusion360 file for design is included and includes some parameters to tweak.
Each piece is only 60 degrees of a circle so it can be composed in many ways and make arbitrarily large or ~50mm (~2in) minimum circles. This could definitely be used with other cabling (e.g. cat5/6).
The author marked this model as their own original creation.
