Glad to hear your Maslow 4 arrived safely, and you’re making solid progress! For adapting the electronics board support, your plan to modify the clamp or create a custom attachment sounds feasible, and it could ensure a sturdy fit with your Kobalt router. As for the sleeve, maybe try thicker materials or even a small hose clamp if it fits securely. For the router’s bottom clearance, spacers might indeed be the best option to avoid any dust cover issues. Good luck powering it up and let me know if you have any other questions along the way!
