I'll be donating 50p to the Inkscape Fund for each unit from the first batch of 300 that sells. Inkscape has been an integral part of creating this product (PCB and print design), and I'd like to give back to you developers for the great work and effort you've been putting into this software!
I'm writing this to you in the hope that you'd be interested in this story (and perhaps PCBmodE and product) but mainly to hear feedback.
