Hi everyone!
I'm looking to make a stamping tool to be able to easily insert a shape that I often need into 0.3mm sheet metal.
I manage to create the desired shape, and to create a tool that adds my material to sheet metal. On the other hand, I can't get my punched clipping and the 2 round holes. Would you know how to do it.
Thank you very much in advance

Hello @benjamin_co
I don't think I understood everything.
Especially when you say
[quote] I can create a tool that adds my material to sheets [quote/]
Could you publish a flat sketch of the part and a top view of the shaped part?
Or publish your part which must be a sheet metal part I guess.
Kind regards
PS: the first one that evokes the thickening file for the addition of material to a pledge! No but!

Hello, thank you for the help, here is the sheet metal part.
The idea is, from a 0.3mm flat sheet metal piece, to be able to throw this shape everywhere and then to be able to take out a flat DXF to launch into laser cutting
Good evening
I just looked at your piece and there is no difficulty in making the holes.
However, I allow myself a friendly remark, you complicate your life for nothing.
You start with a volume that you build in several stages and then transform it into sheet metal.
Your piece can be made in a single sketch and two folds, which will allow you to take into account the loss at the fold and to have the folds more in line with the reality of what will happen in the workshop.
If you have a little time, tomorrow morning I will make you the piece entirely in sheet metal from the first and only sketch.
Kind regards
Oh thank you, it's super nice! I can't wait to see how you do with the sheet metal module for the future, it could well simplify my life!
The point especially on my side is to be able to keep the "tool" in memory to be able to reproduce this shape regularly on several pieces. And often more than 50/60 times hard each part
Hello
I think the tool for you is like this.

However, this function cannot be flattened. So the best is to cut + fold as Zozo said.
Disadvantage of sheet metal functions: repetitiveness. Unable to use repeat for folds. If this cutting + stamping has to be repeated dozens of times on different sides then the punching function is more suitable in my opinion.
Hello @benjamin_co
Small question, what is the point for you to have such a large space between the flat part and the Z-shaped part.
In reality, it all depends on the manufacturing technique. It all depends on the quantities over a year
1°) The simplest is punching and then folding two folds
2° an awl that does both the cutting and the shaping (a bit like progressive VS but very simplified press tools)
3°) The cheapest of all tools is laser cutting with cutting width reduced to a maximum of 0.5 or better than the width of the laser beam. Then two folds with a hydraulic or manual bending machine.
It has not escaped your notice that the double folds cause the round of the central part to be off-center by 0.4 mm. But to hang stuff it probably doesn't matter.
Given the size of the room, you would be better off simplifying it (see note on the attached image)
While waiting to know more, I make the part for you with the machining solution N° 3
Kind regards
Hello @soring 
From my point of view they are small unique parts, which are either screwed or riveted (see the two holes) on a sheet metal or any frame (including plastic)
Kind regards
Yes, if it's the same part, folding is enough. By using the " offset " function, the misalignment you are talking about is calculated automatically.
@Zozo_mp So!: No, these are not unique pieces, it's a shape that I repeat on a 0.3mm copper sheet. In fact it's used to make contact on a battery. There is a spring behind in the 1.5mm.
It comes out in laser cutting. The 2 holes are simply to index a very simple manual tool (sort of shape/counter-shape in 3D printing) to come and " preform " the tab. The latter then takes the final shape when it is stuck under pressure between the battery and the spring.
I want to make it clear that this is not a professional application, so laser cutting and 3D printing, that's about the maximum I can afford 
And it's going very well considering I don't have many parts to make.
@soring it works well with this " punch " tool that I slightly modified to stick to my dimensions. On the other hand, the part does not " flat " when I ask it, to take out a laser cutting DXF. Is this normal with this tool?
Here is the piece made with a laser cut and two folds.
Unfortunately I'm in Version 2022 that's why I made you a little video in addition to the file
Kind regards

Sorry I misunderstood because I started from the piece you posted.
With the two methods we offer you, you should be fine.
In any case, what I offer you allows you to control the dimensions and the deformation due to bending.
The offset function offered by @soring is very good of course 
Kind regards
PS: I don't know if the orange piece you published is made with our methods or the one you used in the first post' it's important to answer your question of the flattening + DXF.
You have to dissociate the cutting and the folding. A drawing where everything is flat according to the method I propose and then you can do your DEXF
Like in real life where you will first do the laser cutting and folding then in a second operation.
A second plane for the folding operator.
But let's bet that my super-fortiches colleagues offer you a more elegant solution.
I've never been confronted with this kind of PB 
I haven't redone everything but you'll know how to do it
Which I'll do in this case, if I want to show the flattening.
Since we have a reason for repetition
I thought about it but I abandoned this idea because, after merging, unfolding was no longer possible
I will go back to what I said. So yes stefbeno solution works. The unfolding is done correctly.
Proof by example (SW19).

"Funny " thing , you can't make a thin cut in sheet metal.
Thank you all for your help!
It allowed me to make a lot of progress, but also to realize that I don't necessarily need to see the part unfolded in my general assembly.
So, I tell myself that I can very well be satisfied with simply placing the flat cutout everywhere.
With this in mind, do you know if there is a tool that allows you to " record hole/cut shapes" and place them regularly on parts? I also often have the case of cutouts to place connectors in partitions, mount PC-type fans etc...
I have the impression that we can do it with the toolbox, but I've been circling around for a few hours without getting my way.
Indeed, I do have a " hole " saved that corresponds to my cut, but when I try to place it, it is impossible to fit on a sketch or an existing element. And once placed, it is no longer possible to move it...
I attach a piece with a piece of sheet metal containing the cut in question.
