Arctic Tern bracket?

<< < (2/3) > >>

Woof:
Since a bracket hasn't magically arrived I made one. I'm currently waiting for the sheet metal version to be fabricated (a week or so) which if I'm happy with will document/arrange how to have more made. I'll also make the CAD files freely available, and it's 3D printable at a push.

A few things are of note:

* The Arctic Tern's connectors don't extend far enough on the board. The mini-HDMI are too far back by a few millimetres, which means the bracket design is a compromise between correct PCIe mechanics and access to the ports.
* (So I created two variants, one with this compromise, and another spec-correct but the ports blanked off.)
* The mounting hole at the top of the PCB is in a really odd place, so needs an L-shaped bracket to connect, and the bracket needs to pass over traces, so will need extra insulation.
(I've attached the work-in-progress CAD files for anyone interested, in DWG and IGES format.)

ClassicHasClass:
Nice work. What are your plans for it?

Woof:
No plans, I made it to scratch an itch. I wasn’t willing to balance the Arctic Tern card in a vertically mounted mobo without a bracket. I’ll post more once I have the stainless steel version in my hands.

I also wanted an excuse to try the sheet metal folding workflow in BricsCAD (like AutoCAD, better in some ways, worse in others, but importantly without the subscription licensing).

ClassicHasClass:
No, I mean for the Arctic Tern :)

Woof:
Ahh! A few plans: the most uninteresting was to simply to boot my T2 faster, the more interesting being looking at FPGA brute force implementations of some the graphics work I do. Unfortunately time ticked on, and since I couldn't just plug it in (then my T2 got gutted for another up coming project) I ran out of steam.
