Laser cutters are awesome. They can cut and etch a variety of materials including wood, acrylic, and leather. Laser cutters are one of the favorite tools of makers, artists and engineers alike. I used a laser cutter at TechShop (RIP) to make an acrylic cover for the SparkFun clockit kit. I used 1/3″ clear acrylic to sandwich the circuit board. The cutout design is based off the original PCB design done in Eagle CAD. I replaced the original push-button switches with switches that extended up through the cover (about 1/4 inch). The design file (done in Corel Draw as that is the preferred file format used to drive the Epilog laser cutter) can be found here: Clock-v12_brd_laser.zip.
