The buttons are made of two parts and they have to be glued together, which is a sticky job for the fingers and the glue makes stains on the acrylic.

So I build a template. 2 Parts are made out of acrylic and 2 out of wood.

4 Srews keep all in place. I placed the top button part in his tempate. The wood part keeps all in place.

Now the round parts with the template on the top. I put a little bit of superglue on the round parts.

Then the second wood part on the sandwitch construction and with the nuts, all is pressed together for 30min

And the Buttons are ready, nicely aligned and no stains.
