Under desk switch mount box for KCD3 rocker switches - single and double version

I was fed up with seeing cable clutter and plug bars, so I made this 'box' to mount a KCD3 Rocker Switch under my desk. That way I can easily switch on my gear (e.g. computer monitors, speakers) when I need it.

Update: I also made a version for 2 switches. A version for 4 switches will follow on my profile. 

The opening is big enough to snugly fit a 10.4mm x 30.4mm (compressing the spring arms) Rocker Switch (usually called KCD3). I have ordered KCD3 switches with slightly different dimentions of AE. Please do measure yours (with arms compressed ⅔ of the way) and scale the model accordingly for a good fit! 

You can mount it however far recessed you like it. I have it just so far that I can not see it from above the desk, but I see it when leaning back.

I added countersunk holes for screws (I am using T-20 Spax slightly shorter than my desk thickness), but you could also glue it or use any other fixation material. I have added the same model without screw holes as well. 

The holes on the rear of the mount should be used as strain relief with a zip tie and the covering plate should reach far enough so that the connectors are not exposed and can not be touched accidentally.

Tip: It is easier to feed the wires through the box and to attach the wires to the switch before you push the switch into the box.

Hope it helps you to a cleaner setup and let me know if you have any improvements or suggestions :)

Supports: 

Yes

Infill:

20%

Filament:

PETG

Notes:

You can use whatever solid filament and infill you like, for me PETG and 20% was sufficient.

Regarding orientation:

I oriented and printed the screwed version so that the surface that touches the desk touches the build plate, but that means you need to remove the supports from the switch compartment (with needle nose pliers or a Dremel for example) and from underneath the tension relief holes. Removing solid supports from the switch compartement was a bit of a pain, so use tree supports or whatever seems easy to remove, or:

You can also orientate it so that the front (switch opening) touches the build plate and then only the screw holes need (for example tree) support, making support material removal easier, but making the screw holes slightly weaker. If you print the version without screw holes, for mounting it with glue fore example, I reccomend this orientation anyway (already oriented the STL this way for you). Depening on your bed adhesion I would reccomend adding a brim though when standing it ‘upright’!
