I have the router dust shoe sold by Open Builds. I got this when I first built my Workbee in 2019. I have since upgraded to a spindle and made an adapter to fit the dust shoe to it. I would like to cut a proper upper piece of polycarbonate (I have the material) and reuse the lower magnetic part. Some searching has not uncovered a model I can use to recreate and modify that part. There are countless other options that do pop up that are likely better in ways. I'm looking for the easy solution today. Maybe tomorrow I will look at the others. Do any of you know of a source for this file is seek?
