Clip/tie Arduino shields together

Does anyone know of any product that allows you to secure and keep the Arduino and the shields all together so they will not separate or come off by the force of an impact or fall?

I want something well made that blends nicely instead of robber bands or wire ties.

hi
why not use a 3d printer for this problem ?

Unfortunately, I don't 3D printer handy. However, your suggestion is a good idea (if that doesn't exist, then make it yourself).

sure and while you are in it make it water proof :wink:

Now, you are hilarious :grin:

ok you can find lot of 3d printing "service" on the web just make a model of the box you want

Use aluminum standoffs from pololu.com
Pololu - Aluminum Standoff: 3/4" Length, 2-56 Thread, M-F (4-Pack)
or nylon spacers
Pololu - Spacers
and then long #4-40 screws & nuts to secure the stack together.
Measure the distances between your boards and select suitable parts.

is aluminium safe for all sensors ?

I'm already using nylon spacers (see attached photo), but unfortunately no all the shield holes line up with each other (e.g. the proto-shield vs xbee-shield). An adjustable nylon clip will be ideal, but I haven't see one yet so a 3D printer might be able to create one.
