One last "hack" I did was glue cork to the bottom of the key. The smooth plastic had a tendency to skate on the table and the cork lessens it a bit. It also covers and protects the wiring on the bottom.

This was an awesome weekend project! Thanks again.

FB Joe, I love the way the black PET looks, but so far haven't had too much luck printing PET so far. I attached my cootie to a marble counter top sample, with some rubber rug anti-skid backing. It really stays put :-)
I asked at a local countertop dealer about the samples and he gave me a few at no charge.

I posted a make. In my shack I have both ham and non-ham friends that would look at it and see sharp pointy things and want to feel it on their fingers. It was taking too long to file the teeth off so I took another direction. At the hardware store a foot long piece of brass 1/32" thick and 1/2" wide was only $1.99. I also shortened the length of the arm to about 100mm.

A 3d printed interpretation of a classic key all in brass. Printed in PET-G at 150um.


They look great in all brass Joe, nice job! I also shortened the blade on mine a bit from the original dimensions, the stiffer action plays a lttle better.
