@Jason_Smith thanks for the followup. I am working on a convertible bowden-to-direct drive carriage. But it’s taking me longer than I thought.
I have all the files up on github. Once I get it finalized perhaps you could add the link to your github readme, or clone the repo over. I also included several cad formats for interoperability between the different cad platforms.
I am in agreement on dual extrusion. It’s overrated.
I love the design. Great job.
