How about making these grates yourself (and other stuff...) ?

Hi all,

just a quick heads up.
a CNC (=computer controlled) milling machine is now available fully functional for less than $200.
an impression on youtube : https://www.youtube.com/watch?v=1Zc7SWwsNVU

my own (only built mechanically, still needs the brains (included)) is in the attachment.
I bought the kit version, there seems to exist a ready-made version too, slightly less cheap.

since it can make printed circuit boards, it is safe to assume it can also generate PE.
It can also mill plastic and perspex.

Interesting times...

Regards,
Ronald
