I had a need to run some cables. I wanted to keep them organized & protected, but the space was small and I couldn't find any cable chases small enough, so I designed this.

It's designed so individual prints can be placed end to end to create longer runs. 

I print them standing on end, to get the most side to side strength. I use PETg and print with a fairly wide brim.

Being STL files, they can of course be scaled in Prusa Slicer to a desired size.
