Parts for the front of the tagger were printed. Some of the dimensions were not printed precisely enough on a 2+ year old printed. To make sure all the holes were the correct dimensions, drill bits were used to plunge through each hole. This ensured each hole would be the correct size all the way through.


The emitter holders were a different story. They were tapped using an ordinary tap, usually used on metals like mild steel and aluminum (aluminium) but they had no trouble tapping plastic. If these pieces are not tapped, it is necessary to use a nut on them which is a perfectly reasonable solution. If only a few taggers are being built, a tap would be an unwise investment since nuts are so inexpensive.


The drill bit sizes were documented on a tracing of the forward array for reference while the rest of the arrays were drilled. The small 5/32" (4mm) holes were for long machine screws 2 1/2" (65mm). The 1/4" (6.5mm) holes were for the LED holders and the 1/2" (12.5mm) holes were for the laser emitters.
