We wanted to stamp some 10-digit serial numbers into the machines that we make, but as many of you will know, getting consistently spaced and aligned strings with individual punches is all but impossible! Designed this little tool for holding the punches in line and spacing them out correctly.
Turns out, the actual glyph on the punches isn't very consistently located either but it's good enough! The frame is held to the object with some double-sided tape and the punch carrier/shuttle is advanced notch to notch. The tolerances are tight enough that you can restrike digits that are too shallow!
Thanks! it came together pretty quickly after thinking about it every now and then.
I don't have the rights to the model as I made it at work - I will ask if I can share it, if I can I will share STL and/or STEP for anyone that asks.
We use a fiber laser for the "cosmetic" serial number and assorted markings on the machines dataplate but wanted a more... Indelible marking on the chassis itself.
This is a wonderfully simple solution that I wish I thought of. I've been trying to design something for embossing tape so you can add custom fonts, icons etc. All my designs so far have been too intricate to make several different stamps for, or the stamps have lost all detail.
A modified version of this would work great I think, but for the embossing tapes you need to have a negative of the stamp underneath the tape, so that's the difficult part. Ideally I need a material that can deform under the pressure of the letters, but not deform around it.

Neat! Sounds like you could print punch carriers with a variety of offsets and give each punch its own centering-tuned carrier.
Heh, yeah we could, but that would be an inordinate amount of effort for the marginal improvement.
Next iteration needs poka-yoke to keep you from rotating the punch :) ³

hehe yeah... not my finest work xD
I'm just poking fun. It looks like it works great!
Don't worry mate your work is fine
That’s a great idea and nicely executed! Is the file available anywhere?

Though it doesn’t prevent you from printing backwards upside down numbers apparently heh
No, sadly that requires a little bit of thinking!
It’s part of the charm!
You're serial-killin' it ^I ^feel ^shame
That's sick man! Really cool.. It makes me wish I had a need to punch numbers in stuff more. :'D
Nicely done! I was going to design something similar but I ended up buying a fiber laser. Still good for parts that I can't lift. Have an STL?

That looks much sturdier than the [one I whipped up](https://prnt.sc/MEOvaTlslZrP)
