I'm currently working on a project which requires some decent cable management. I need cable trunking, but getting access to it is a bit difficult, and I haven't found a model suitable for my needs. So I decided to see if I could design something that would be robust enough while keeping things tidy. I ended up making a parametric trunking model which allows me to set sizes up specifically for my needs.

I thought I would would whip up some files and share some of the more common sizes of this stuff. The zip file has a range of sizes and lengths that should suit most purposes. Attach using tape, adhesive or screws. Screw holes take 4G screws/M3 fasteners. Dimensions are pretty much on par with commercial stuff.
