Cable clips for wire rack shelving

I'd love to have a real network rack.  But I'm cheap, so I have wire rack shelving, like this:

To make routing of ethernet cables a little cleaner, I created these quick and easy clips.  Now my routed cables look like this:

Use

To use these, first, identify the top and bottom of the clip. The bottom "curls around” a little more, to allow you to temporarily attach just the bottom.

Just click the bottom to the rack, lay the wire on top, and then swing the clip and click it closed.  Here's one with just the bottom engaged:

I have noticed that different manufacturers of wire rack shelving have slightly different dimensions, so you'll need to measure and either use one of the two clips I've provided, or go into Fusion 360 and modify the design.  That sounds scary, but I've parameterized things to make it slightly easier.  Prusa has a great introduction to Parametric Modeling in Fusion 360 to help you.

Customizing for your shelving

The parameters you'll need to modify:

• wire_diameter: this is the “thickness” of the two rails that you will need to clip onto.  Probably around 5mm or so.
• overall_height: the distance from the bottom of the bottom rail to the top of the top rail.  Probably around 20-30mm or so.
• length: how “long” each clip is.  Maybe I should have called this “width”.

Hopefully you have some cheap digital calipers.  If you do, it's easy to measure the wire_diameter:

Printing notes

I printed using a 0.6mm nozzle, 0.3mm layer height, with a variety of different PLAs.  This design probably works fine with PETG as well.

Print them their side.  You're gonna need a brim, and you're gonna need a deburring tool to clean it.  Don't fear the brim!  It's satisfying to print a plate of these little clips and end up with a big carpet of peelable clips:

Thanks for reading, and I'd love to see your makes!
