If you have an Onshape account (it's free) I encourage you to use this link to edit these files directly to your specifications.
Please note: all files/models are rough around the edges (and I don't mean fillets lol), and fitment isn't perfect. I will rerelease an improved instrument dock as part of my broader efforts to create a complete robotic system! Any major file releases will accompany a video being published, so check out my YouTube channel if you haven't already.
And if you've made it this far and are curious why you keep seeing the project name Salai, here's your answer :)
Best Wishes, Bennett
