so we can probably get the main case 3d printed from recycled PETG in slovakia (so EU) for around 27 euro per piece at a low batch size of 50, and the aluminum plate would be like 3 euro. with port pcbs and thermal pad we would arrive at maybe 45 eur bom, so with 30% margin and 20% vat we could arrive at something between 70-80 eur sale price (depending on labor and how much else is in the kit, i guess we put in the thread inserts and rest is DIY)
