Typical 3D printed gadgets are laden with hyper specific parts that increases the BOM cost significantly. I tried to find a completely mechanical toolchanger and only found over-engineered designs with large BOM's and complex assembly. I designed Maxwell's Razor to use as few non-printed parts as possible, the coupling is entirely 3D printed with the most special part being a few neodymium magnets to securely attach the printheads to the gantry. In addition, the docking mechanism is completely mechanical and 3D printed as well. Estimated cost per toolhead (including hotend and stepper) is well under 20USD. Most of the cost comes from the extra stepper and E3D V6 hotend, the design only uses 1 USD worth of magnets for each toolhead.
