Tree of knowledge and power decora plate cover

Hey folks! I have project pics and a funny story.

Pic first! Behold the Tree of Knowledge and Power, a custom two-gang decora plate cover for a cat 6 internet jack and a standard outlet:

I used @cynd11’s Light Switch Cover Design Files for the decora and screw cutouts (decora is the type of plate with the big rectangle in the middle). I increased the width of the decora cutouts by about a millimeter because the outlet is crooked.

“Lovely,” you might think, “but why bother with such a design at knee height? Surely a normal plate cover would do?”

And now it’s story time, because here’s what happened:

I offered to help a friend fish cat 6 from their router to their office. I’m an electrician’s kid; I’ve been fishing wire since before I could spell fishing, wire, or “good grief why do I always forget how annoying fishing wire is!?”

The walls did not cooperate (they never do).

Several holes in drywall later, we finally found a wall that actually had open space in it, next to the outlet pictured above.

We promptly broke the drywall between our new cat 6 jack and the outlet:

Not wanting to have to patch drywall between or next to the boxes (because uuuuuuugh), I came up with the thrilling plan to make a custom plate cover. Nothing says “not to day, satan” like covering up your mess with plywood, am I right?

So we begin planning the cover.

My friend’s partner sees the planning and asks, in full innocence of the destruction we have wrought, “why are you making an outlet cover shaped like a tree?”

Me: “it is a tree of knowledge and power.”

My friend’s partner: …?

My friend: “Because it has the internet and an outlet.”

My friend’s partner: “Yeah no I get it but do you really need to go that hard at knee height?”

My friend: “We are dedicated to our craft.”

Me: “and to not patching drywall

My friend’s partner: “what?”

Me: “what?


So anyway I told this story on twitter and was told to come post it on the forums, so here is the very artistic cover that we were definitely planning on doing the whole time, and which exists only because it sparks joy and not because the wall behind it (and all the other walls in that room, why is there masonry inside interior walls, why I ask you, this house was built in the 1960s, what foolishness is this) sparks despair.

Some progress shots:

We printed a few paper fit tests, because nothing in this house of leaves is plumb. Here is one of them, pictured with the Human Digital Control tool we used to cut it after deciding we couldn’t be bothered to test paper cutting settings on the Glowforge:

Then we cut the front out of medium baltic birch. Here’s a final test fit, sans backing layer:

We used more paper tests to shape the backing layer, then lasered it and glued it on. The backing layer holds the plate flat against the wall. After it cured, we added aluminum tape as a spark barrier:

And the finished plate, in service:

The moral of this story is that you’re not in trouble if you put a hole in someone’s drywall. You’re only in trouble if you get caught.

So this is what you have been up for this last year. Fun write-up and project.

I love this idea and it turned out great! My brain can’t comprehend that the wood is on top of the drywall for some reason. I know once I ‘see’ that it is it will always be so I guess I just need to keep on looking!

My primary functions for the past year have been day job, parenting, and staring into the middle distance.

Also a bunch of small projects I didn’t post because they were neither funny nor edifying.

Mostly silverware trays. Being able to make silverware trays is like owning a truck but for kitchen drawers instead of moving stuff.

Stares into the middle distance everyone wants a tray.

But in all seriousness the workshop has not been entirely quiet; I’ve just been quiet about it. I’ve been up to more ceramics and sewing, both of which I use the laser to cut tools for but it’s not usually a key player. And I’ve been getting the workshop into progressively more useful shape. I might even be back to ceramics + lasers testing soon.

I know. The shadows (I think) make it look like the plywood is behind the drywall.

I really like that solution. That story was great, aligns perfectly with my reality.

That is fabulous! I’m so glad you posted :smiley:

I enjoyed the story as much as the final project. Talk about making a silk purse out of a sow’s ear!

I would love to see how a frilly line art design would fare on a thin dry slab of green Raku clay if dumped in water so the green part would fall away, and then properly glazed and fired. :heart_eyes:

If you do so please post photos even if it does not work.

I can do a different topic for this but based on my initial testing, this won’t work–on already fired tile, the laser heats and cools so quickly that it vitrifies the tile into glass (which sounds cool but it’s not pretty; it looks like a melted burnt line). There’s another thread on here where someone tried lasering greenware and it just produced grainy vitrified lines; nothing that’d hold together.

What does work well is using the laser to make molds–I use 3mm baltic birch for this, dust it in cornstarch, and have gotten some fairly delicate designs that way.

I too enjoyed the write up and the piece came out great!
