The only thing I'm concerned about is that the original stem is designed to be able to flex enough that it pushes into the guide hole and then springs out the other side to retain the key and stem. i.e. it's using the elastic property of the original plastic, which feels like polythene.

And that is a concern for me too, so I an going to try and attach the original stems, I have one setting just now :)

And another out of the mould :)
Look better again and because I added tiny air holes the reverse is way better formed:

The other difference here is that I used the original keypost to see if it would work, the only caveat being that I needed to fill the hole in the post, but not so much that the end wouldn't flex so it wouldn't go in the hole.

I've done the same with the green keypost which is currently in and setting. I think once painted they will look just fine.

Definitely satisfied with the results

So I tried the number one key that had the original keypost:


And I think with some fettling it'll work. How long the join between the original stem and the keycap will last, I don't know though.

At present it is a little sticky. The ESC key is a bit tight and requires work, though it does fit, and I think that is due to the remaining original keypost being shorter then that of the one key and the rest of the shaft in epoxy is a smidge thicker than the original.

Again I think it'll work with some fettling.

The clear keycap and original all epoxy keys do fit, but for some reason they posts are a bit short.

Lots to think about.
