Metal Electro Etching Enclosure

I am a blacksmith and was looking for a better way to mark my projects. I turned to metal etching and watching a youtube video and finding this tutorial https://www.instructables.com/Steel-Etching-and-Marking-from-a-DC-Adapter/. I decided to make one of my own. The video referenced this tutorial but took it a step further and designed and 3d printed a box enclosure for it all to nicely fit in sadly the video doesn't share the printable files and is many years old now. (I asked if the youtuber would share or sell his files but got no response to my comment) So I set about designing my own in fusion360. And this is the end result.

What you will need to put the box together
3d Printer and G-code slicer (I printed in PLA with a 20% infil)
4 - M4 X 8 screws
2 - M5 X 20 screws and nut for the post
1 - 6 post 3 position switch (https://www.amazon.com/gp/product/B07HHVFS5V/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1) or comparable
