Took me a while to make mine, because I ended up 3D printing a CNC machine (https://www.vicious1.com/) in order to cut out the needed aluminum plates. The aluminum was just scrap I got from someone else, so that saved me a lot too. My first test of the CNC machine was engraving a giant Farmbot logo on the front of the device (facing outwards towards the neighbors ). All custom parts were 3D printed out of scrap recycled plastic, and the rest were bought from the Bill of Materials section (that made it very easy, so thanks!)
