I have been trying to build a sliding keyboard phone attachment for a while now, but can’t seem to get anywhere.
I tried double hinges, but they had too much slop. I tried a detachable fixed clamp, but that cannot be put into a pocket.
So now I am looking at making it a slider like the Motorola Droid 4 I used before.
I do have a 3D printer, so making clamps and cases/housings is no problem.
But printing a sliding mechanism will probably not result in anything remotely durable.
So my question is, what kind of sliding mechanism could I use for the sliding motion? The requirements are as follows:
I looked at linear rails, but those are too large (especially the carriages). Also I fear that the ball bearings wouldn’t like the dust.
I figured that just bent steel profiles could do the trick, but I couldn’t find anyone who made Z profiles with that small of a middle section (I would need it to be like 3mm or so).
I am very much lacking the terminology to know what to search for.
