This is an extendable straight rigid cable guide. This design is especially useful for extending / adjusting the guide length AFTER installation.
Each guide set consists of two models: Inner, and Sleeve. The Inner easily slides inside the Sleeve.
There are three sizes of guide sets provided: 4mm inside diam, 6mm inside diam, 8mm inside diam. The 4mm inside diameter will hold a 16-gauge wire pair. The measurement applies to the Inners. Print the corresponding Sleeve that matches the chosen Inner.
As supplied, each model is 18 cm long; providing a guide set that will expand from 18cm to <36cm.
Use a slicer to modify (i.e. scale in X direction) the length.
Use a series of inner-sleeve-inner-sleeve-etc. to achieve really long lengths.
Rotate the inner vs. sleeve to fully capture the cable.
