> If you like I could mill you some, and send them to you for your kit.

Thank you for the offer! However, the design file would be very much more useful (assuming you want to share with the world).

I will post it. But you cannot laser it from steel as it has to be elastic. I used 1.5mm FR4.

Just in case you or anyone else reading this isn't already aware, take care when milling FR4. Most FR4 is some form of fiberglass and fiberglass dust may or may not be carcinogenic.

The recommended max respirable level is five milligrams per metre cubed and if you know how to measure that then you know a lot more about it than me

If available I make a point of using FR2 for milling, it is paper-based.

Understood. Lot of plastics that cut nicely with a laser. (Milling is slow (=expensive) in a product.)

I mill tons of FR4 and Carbon fibre, and have a vacuum outside, so all dust flows out of my house
And..it mills much faster then a laser, and you do not have burnt surfaces.

Here is the dxf file.
