Sliding Outlet Cover: Knox Edition

So you've tried my other sliding outlet cover models [1, 2], but your kids are too smart and persistent for their own good and figured out how to open them? Time to step up your game with the Knox Edition. No more messing around, these things are staying closed. 

 

This edition comes in two customizable variants: Tool Assist and Padlock. 

Tool Assist Variant 

The Tool Assist variant is very similar to the previous “Improved” model, using locking tabs to keep the cover closed. But this time there's no protrusion to push. Instead, a separate unlocking tool is printed that inserts into the two tab holes to release the locking tabs. 

 

Additionally, a small bar that sits flush against the wall blocks the use of improvised tools casually slid in against the wall; the hole is slightly offset from the wall, requiring more dexterity to find with improvised tools. 

Padlock Variant

This variant is the nuclear option, for when you want to leave nothing up to chance. Forget locking tabs and small holes, this one has a large hasp latch hole for properly locking the cover closed with a real padlock. 

Customizing

The provided print profile contains the cover sized for my 115mm x 72mm outlet faceplates. Your outlet faceplates are not the same size as mine, you HAVE to measure yours and customize this to match. The print profiles are just illustrative of the different variation and print orientation options. 

 

Use MakerWorld's built-in Customizer (or a local copy of Fusion) to create a custom cover that matches your outlet faceplate's dimensions, and the depth that you require for your application. See the notes for the variable names for more information about what they control. 

Printing

Customized models are NOT automatically oriented the right way for printing. Please download the provided print profile, open it in your slicer, create a new plate, and drag-and-drop your customized model file onto the new plate. Then orient your custom parts the same way that they are shown in the example plates. 

 

You will need to separate the downloaded model into separate parts using the Split > To Objects option in your slicer (right-click menu for the part). 

 

Using the same orientation as the print profile is especially important if you want to ensure that the print seam does not end up on a visible surface of the cover piece. Alternatively, manually paint the seam onto an inside surface using your slicer. 

 

Installation

Installation is the same as the previous model, see the Installation section here: https://makerworld.com/en/models/2136283-improved-sliding-electrical-outlet-cover

Tool Assist Removal

Flex and slide the tool over the cover and slot both ends into the side holes. 

Gently press in and slightly towards the wall while pulling up on the cover until it releases. You should only need to press the tool in a few mm on each side; pressing too hard may cause the tool itself to get in the way of the cover and prevent it from opening.
