More info on fuses. For Milwaukee we knew what cars were coming so we did not buy every kind of fuse possible.)
In Milwaukee we did not have Burke designed medals, so we made our own. Your quantity of Acrylic may be dependent on how many medals you need. (There's a formula somewhere.) Obviously you need a laser cutter to make them. Note that we should update this as Patrick uses different color & thicker material. YMMV.
