This was made from two bits of Perspex that I used my CNC to engrave Open and Closed into then used a string of LED's to edge light them. A short length of 25x15 trunking and hot glue holds it all in place.

A simple three position switch selects Open, Closed and off.

I did say it was simple :-)

how deep did you engrave it and what kind of bit did you use
Hi there,<br><br>I built a CNC a few years back that basically has a Dremel attached to it. The bit I used was a sort of cone shaped coarse grinding bit and at high speed on the Dremel but low speed on the CNC it does not melt the plastic.<br>I also ran the program twice at two cutting depths hence the slight offset on some of the letters.<br><br>I have done one free hand but it takes a lot longer to do and if you sneeze half way through.....<br><br>Regards<br><br>Darren
