Designing a new Atom keyboard

Post by roland » Fri Feb 13, 2015 8:03 pm

There has been talk, maybe too much talk about the shortage of Atom keyboards. And housings too. Maybe we should just put the cat among the pigeons and start this project. I'm willing to investigate :mrgreen:

Who on this forum has (access to) a 3D printer that can print an object of about 380 x 280 x 65 mm? And what would it cost?

An alternative is a smaller box because the main board can be placed below the keyboard, just like the Electron.

I think that might be a little optimistic for home or hobby printers. The 'Mendel' iterations have a print volume bounded by an approximately 200mm cube for example. So anything larger would have to be printed in sections and designed with dovetail joints or pegs/sockets or similar. Or just glued.

How would a keyboard be printable in any case ? The keycaps could be of course, but how would you intend to do the actual keyswitches ?

Cheers,

Hi Phil,

I didn't want to print the switches and key caps. A set of keys and caps will cost about €60-€70. And that's for the Cherry keys we talked about in the main board thread. I have two samples of those keys and they are really nice (although also really expensive) keys. The caps are smaller than the original Atom caps so the Atom case has to be adjusted to the new keyboard size. And that case is the only object that has to be printed with the 3D printer.

Greetings,
Roland

Print volume looks tricky .. The printers that print to this size like the Fortus 450 look expensive ..

That makes sense Roland. Maybe something like 'shapeways' would be feasible, no idea what the cost would be though.
