I'm highly retarded, and have been pondering for a long time on how to do 3d print assisted depth etching.
3d etching.
For a long time I didn't have a printer, but I do now and I am now exploring this possibility.

Here's my basic concept:
A piece being worked on falls onto a surface which etches it and keeps falling through it, simple as that.
A jig is designed in 3d modeling software which allows a piece to fall onto the cutting surface. The jig is designed in such way that the work piece can be removed and inspected mid-process and placed back in roughly the same position.
The cutting surface has a small ledge which isn't electronically conducting, this is to keep the work piece at an ideal distance from the cutting edge.
In my case the piece being worked on is a standard M16 bolt.
The cutting surface has a electricity conducting mask on it. Normally when etching you would use a negative mask, but in this case I will use a positive mask.
In my retarded mind tinfoil works for hats so it will work for this too, so I did mask out of it and glued it in place.
I bought a second-hand laptop power supply and modded it with alligator clips to have a source of electricity.
Assemble the thing, put it in salt water bath and inspect results in 2 hours, then try to improve the process.

What this thing is suppose to do is cut a slot in the bolt, or catch on fire and burn. This is an experiment, I’m curious to see if it could work.

I tried that. It did etch, but the sludge is a major problem as it conducts electricity at random, and burns through the tinfoil mask.
I have some aquarium pumps which I am going to try and connect to this jig.
I thought about spraying the salt water solution directly on the cutting edge and having it fall in a waste collection bucket.

But before I proceed I figured I could make a thread about this. And more importantly ask if anyone has tried this.
