A thread to prove I'm not ONLY about advocating for Tobacco Harm Reduction for nicotine consumers.
I also get into photography & videos (mostly time-lapses), electronics & 3D printing.
For the first two, see my YouTube channel.

For the latter two, here is a project I'm working on at the moment. It is a 3D printed box for electronics.
The thing is, I /could/ use a Jiffy Box (below), as U might buy from @JaycarAU.
But the problem is, they are a 'one size (OK 3) fits all' approach.

..and the thing is, they are usually the /wrong/ size.
One variant might have enough length & width, but not enough depth.
Another might have enough width and depth, but not be long enough!
The next bigger one is always TOO big.

If all three dimensions DO happen to be suitable, the 2 (or 3, in the larger ones) internal channels for holding the components in place, will be in the wrong position!
So I decided to get around all these problems by creating a 3D model for a components box for which I can specify all 3 dimensions as needed, and with the vertical support channels side-by-side all along the inside.
The first few channels are marked in red.

The part you see is actually 3 pieces - the main box & 2 pieces slotted into the ends. One end has a KeyStone Socket that can accept a multitude of standardized electronics connectors (USB etc.) which allows me to bring power & data (e.g. from sensors) into or out of the box.
The left end has a blocking plate (no 2nd opening is needed for this project).
But one aspect of the design was fraught with problems. Those channels take a u-shaped fitting, which slides down into them.
That fitting supports a board which can be drilled to secure the actual components to.
That fitting supports a board which can be drilled to secure the actual components to.
But my earlier design on the right (#1) had problems:
1) The horizontal extensions were intended to support the 'component board', but they took up an extra 10 mm of width!
2) They had to be raised to allow sliding the component board back and forth (the screw heads holding components would catch, otherwise) so some depth lost as well.
3) There are cases when a project might need multiple levels / layers of component support boards.
So the design on the /left/ (#2) fixes these problems by using a 'saw like' ridge running up either side of the U shaped support, along with a component support board that itself has a tooth running either side along it's length.
Now multiple levels can be used at full width!👍

Problem solved?
'Further research' is required.
What? you didn't think terminology from trawling through scientific papers on THR would creep into this discussion?
Fools! FOOLS! 🤣🤣
Fin. .. or is it? 🤔
