I’ve been designing a mod for the existing mount in my head for the last day or so. What I’m planning is take the standard lower mount, join the halves together but leave it oversize, kinda like an oval. Then put in a part on a screw that clamps the router to the back half of the oval. That way, there’s no screws holding two thin pieces of plastic together. My biggest problem at the moment is the moving part is captured in a groove, and petg doesn’t do overhangs or support very well. PLA is garbage in my opinion, good for paper weights and vases and that’s about it.
