this is a universal base plate capable of accepting various linkage and z axis solutions. It is open source so if you have access to a laser/plasma cutter I can send the DXF to you. https://www.2twentytwosteel.com/ did this prototype sled for $55 for us. We will be having it cut in bulk locally.
see website for more info and to order. If you have questions best to email us or call as we do not visit this forum every day.
