I used to etch PCBs at home a lot when I was in college. I used a glossy sheet to print the PCB Gerber on it. Most times I had to etch multiple PCBs and then two things used to happen when I used the same glossy sheet again and again. They were expensive where I lived. 1. The glossy sheet would get blackened due to printing multiple times on the same side. 2. I did not have a printer so I went to a cyber cafe to print and he would charge me for every print even though I was printing on the same sheet. 3. I had to carry my laptop to manually adjust the gaps and often it got screwed up. So, I wrote this script [0] that would combine the gerbers in a single PDF that I could print in a single go. I used it a lot and saved a lot of Money to keep the hobby alive :) [0] http://rohitg.in/2015/04/17/BoardMerge/ http://rohitg.in/2015/04/17/BoardMerge/
