Description
My 1 year old nephew loves unplugging and switching off various power points around the house, so I designed this inspired by some others I found online. I assume this would work on any outlet/power point in Australia (or other countries that use this style).
To install, the outlet needs to be unscrewed from the wall so that the backing plate can be hooked around it, then just screw the outlet back in to secure the plate. The box simply slides on the rails.
The overall design could probably be a bit more refined but so far it's doing the job I wanted it to.
After going through several iterations I finally landed on something that is easy to print, and very simple to install.
The lock is hidden! From the outside you wouldn't even know it had a lock mechanism - perfect to prevent curious little hands from possible unlocking it.
I have also just utilised the rounded edition from version 1, so that all models are a lot safer for wandering toddler hands.
The lock slides towards the wall, underneath the now shortened rail, which prevents the cover sliding up the rails until the lock is pushed back again.
I have included 3 different lock versions:
Left Lock: Looking at the box on the wall, this lock is on the left side. Useful if your outlet has an angled plug, or large brick that would interfere with a lock on the other side.
Right Lock: Looking at the box on the wall, this lock is on the right side. Useful if your outlet has an angled plug, or large brick that would interfere with a lock on the other side.
Double Lock: The most secure, requires both locks to be open, prevents accidentally knocking one side loose and it just easily lifting up.
Effectively, use whichever lock versions allows your plugs to still fit inside the box.
v2.1 - New lock system added. Full differences explained below:
- Rails on wall plate were shortened - this allows a sliding lock to push out below the rails, preventing the box sliding up the rails without unlocking.
- “TOP” text was embedded on the wall plate - the shortened rails now require the plate to be installed in a specific orientation.
- Pointy box versions were removed - profiles now only include the rounded versions.
- 3 different lock versions exist. Left, Right, and Double. Explained in detail in core description.
** UPDATE 3 ** Both print profiles now also feature an option for rounded edges per a request I had.
** UPDATE 2 ** I have now added a second profile, that is used for vertical outlets (and possibly light switches I suppose?) due to a request. This new profile includes both the larger and thinner box.
** UPDATE 1 ** I have added a second box that doesn't protrude as far - should be suitable for regular plugs. I have used mine to cover Foxtel Cables (new pics added)
