I'm on the hunt for a pair of FE85s, they are like hen's teeth though. Found a place in the States that have them, but they want as much as the speakers for shipping.
Thanks for the STEP files
@Yaka, I've just had a look in Fusion360 and you're right - they should fit on the Shapeoko 3. Not attempted toolpaths like this mind, so I'm thinking of gluing up some MDF to use as test pieces before committing the job to some nice wood.
Do you happen to have any insights from the dude that did your CNC work? What mills/types of paths he used?
