Support multiple devices in one mount

[MoshiBin]

Some devices are smaller than half a 10" rack, allowing for multiple devices in one mount.

In my case, I want to mount both a MoCA adapter and an ONT. These both fit within 1U with ample spacing.

To visualize this, I hacked the script to add an "offset" variable, rendered each device independently with a different offset, then overlaid both models in the slicer. This won't work since the front panel of each exported model interferes with the hole of the other, so it's just to visualize what I want to achieve:

If this can be extended enough, this can pave the way for "blade" mounts, for example SBCs like the Raspberry Pi mounted vertically in 2U can likely fit ~6 units.

I'm not comfortable enough with OpenSCAD to contribute this myself, and the LLMs I tried did an awful job trying to add this feature.

Thanks for the detailed explanation. I see that this could be valuable. I'll look at a way to make this flexible while still intuitive for users.
