FYI I marked up the Ettus B210 Plates drawing to fit the Hammond 1455L1601 face
plates. I never got a reply from Takachi when inquiring about the enclosure,
and someone else posted on the list that the Hammond case fits nice, and it is
available from Mouser in the US.
It?s really just a matter of shifting X coords by -3.6 mm and Y coords by
+2.4mm. Cut back the enclosure 8 mm to fit with the provided ABS bezels, and
the SMA flats will be flush with the plates. Also, if you use a 1/8? end mill
to cut a slot for the USB3, it fits the connector shroud nicely and provides
mechanical support. The DC jack coordinates are also offset for the width of
an 1/8? end mil.

I'm going to have to put this on hold for a while, for a couple of reasons:
- I haven't gotten much interest expressed, and bulk/volume only
works if there's more than 2 people. :)
- There's (apparently) pending changes to the boards coming, which
will affect the enclosure penetrations, negating any work done now
Thanks!

Subject: Ettus B2x0 enclosure group buy/machining interest?
I've been doing a little research on cases for the Ettus B2x0 series, and
wanted to talk to the group about interest in some sort of group buy, or at
least group machining. I have one of the Takachi enclosures, which is a
perfect fit for the board, and the price is about 21 USD in the volumes that
we're likely to do. That includes silver finish, and aluminum endplates
(unmachined). They have the same enclosure with ABS plastic endplates,
though, for about 8 USD. I don't think that the plastic endplates will work
very well, though.
I have a local friend who owns/runs a mid-sized machine shop, and will be
taking him my enclosure to see what the cost to CNC machine the aluminum end
plates. I'll have him look at both machining Takachi-supplied end plates
(so, the 21 USD enclosure), as well as making end plates from blank aluminum
stock (so, using the 8 USD enclosure). He can also do laser engraving, so
will get pricing on labeling the end plates as well.
The absolute easiest thing for me/him to do would be to just machine the end
plates from stock, and you get your own enclosure from Takachi. But, while
the Takachi company was extremely pleasant to work with, there's still the
back and forth across time zones, etc., and I'm not sure about the costs of
the different options yet to say which would be the absolute cheapest.
How many people would be interested in a bulk buy/machining? How much would
you be willing to spend for a complete enclosure, with CNC-machines end
plates for either the B200 or B210? Both of those numbers will help me when
I talk to my machinist.
Also, Ettus folks, if there's any interest in me getting you in contact with
my machinist for a possible "official enclosure", please contact me offline,
and I'm happy to put you in touch. I have a day job, and would rather spend
my free time playing with my B200 than coordinating shipping, etc.. :)
Thanks!
Robert

Are there any details on what the aforementioned board layout changes are for?
Should I regret buying/getting the current rev of the board? :(
Thanks!
Robert
So, something that people should be aware of is that the B2xx board layout will
change slightly for new units, starting sometime
soon (for a wishy-washy definition of "soon").
That won't affect people for boards they already have, but if someone is
planning on doing a stock-pile of enclosures as a bit of
"free enterprise", be aware that the board/connector layout is likely to
change in the coming weeks.
Also, if you're considering extruded plastic type enclosures you might consider
that such enclosures will provide zero RF shielding, which is one of
the two prime reasons for having an enclosure.

Just adding mounting holes, changing to a USB3-A connector instead of
micro A, and moving some things around to accommodate those changes. No
functionality differences.

Thanks. The connector would be nice; I'm worried about the micro connector, a
little bit.

Nothing "functional". Just addition of mounting holes, and a new USB
connector.
