Both MK1 and MK2 chassis included. These are intended to be CNC cut with a CNC router but if you have a big enough 3D printer you could possibly 3D print them, I dont know how strong they would be though. I have included 2mm and 3mm thick versions for ease of use. Make sure all the holes are 3.1mm and you wont have any issues putting screws through it. I have made both and both fit perfectly with all the other files I have made. Please check out my Youtube video on the subject here - https://youtu.be/A3WvQG3Msh0?si=osWnvfyYB94u8PTG
