More domes

I've almost completed my Mk4 RepRap Milestag gun and I needed to make some sensor domes with mountings that allow me to fasten the sensors to a baseball cap. I started out by maing six more domes from acrylic sheet as detailed here. To do this I modified the dome mount I made some time ago. I needed to modify the dimensions slightly as my domes have an internal diameter slightly larger than the ones I got from Lasertagparts. Here are the two parts:

Rather than potting the PCB and dome in place, my design uses three screws to hold it in place. This allows it to be dismantled for maintenance.
