The batch number from my box is 54108
I received my MicroView yesterday, and confirmed that it has the bootloader. Is there a way I can provide the batch number to help your troubleshooting?

As far as I’m aware, STL doesn’t include units, so any exported models have to specify both the scaling and units. Specifying units and scaling is redundant, particularly if you’re working in metric, because units of meters with 100x scaling is equivalent to specifying units of centimeters.
When using Solidworks, I prefer to use actual units rather than 100x units. This makes it easier to measure and verify things in my model, esp since solidworks understands and models units, not just values.
You say that models should be exported with ‘100x’ scaling, but you don’t specify units. I think it would be more useful to specify units (m, cm, inches), since they’re directly measurable.
My thoughts exactly. I do all of my modeling in Solidworks, so I’ve included my source Solidworks files in my pull requests. There’s more information available in the solidworks files, and including them will make it easier to improve models that are already in the repository.
I suggest adding a file naming convention so that it’s easy to associate parts with their solid models. For those of us making models in other formats, I think it makes sense to include both the source file and the exported STL in the repository.

The Electronics Parts Supermart in Santa Maria would be a good place to investigate; they’re one of very few electronics parts stores on the California central coast, and they carry a big selection of older electronic kits and things. I think I’ve even seen a few kits for old Apple or Apple ][ daughterboards in there, and they’re one of very few physical stores I’ve encountered where you can buy a MAX-232.
They don’t have a website, but they’re easy to find on Google.
Oh, and they have a working tube tester in the back.
Seconded; HSC would be a great fit. They have a great selection of simple components and physical widgets, but lack cheap microcontroller kits and accessible sensors.
I'’ve been into a lot of ACE hardware stores, and they all seem to be very down-to-earth and in touch with the local community. I’ve even been in a few that have extensive selections of model trains (one of my other hobbies), so I think they’d be worth investigating for electronics as well.
