One more SOB case design

Postby systemstech » Fri Aug 10, 2012 7:49 pm

One more design added to the pool.
This design needs more refinement before going to get fabbed.
But here is a look.

I rescaled Filip's board and used it in the stack. The BPv3.6 sits under the board adapter screwed from the bottom up.
All the layers are welded with solvent but for the last two the makeup the bottom lid and those two are welded to each other.
Four 4-40 or 3mm screw fits nicely recessed in the bottom lid. The screw holes on one of the bottom spacers needs to be tapped, also the board adapter. The bottom spacer that gets the tapped threads gets welded to the case.

The USB port should be a little wider maybe.

The screws that close the case are at the bottom and rescessed

Need to work on the top layer some more.

I spent all day working on this I am not that good at it yet but getting there.
I have to figure out a way to post the large files.

Why not thick spacers instead of two thin spacers each side? One thick spacer will cost less than two thin ones. :)

Actually the third column is just extra just in case I break the thin acrylic and I just happen to have a piece laying around that is 3 x 250 x 250mm. You can use 6mm or 1/4" acrylic it all depends on what you have on hand or your cost at the acrylic shop you use.
The less joints you have the better. When it comes to weld-on #4 that stuff runs like water and will burn or stain the surface of your nice clear acrylic, I've had it happen many times until I got good at it.

if you use the super thin pieces it would be wise to use an acrylic glue to laminate them together

this is what i have used, it dries clear and if applied in thin layers to avoid bubbles or excess escaping the joints look like it was never glued at all.

I keep a tube of that stuff around the house all the time. #16 is great when you need to plug up a hole in a fish tank. that and a little acrylic shavings from a file and you could make a paste to fill cracks.
