Created a new replacement dust adapter for my circular saw that replaces the original one. The original didn’t fit my Nilfisk Multi II 30 shop vac. Now I don’t need to fiddle with the adapter I first made.
Sharing if someone has the same combination: https://makerworld.com/en/models/996710
It has held up fine! Super sturdy and not a single doubt in my mind that it will last as long or longer as the original. I can put real heavy loads on it without any issues. I don’t think the layers are a problem in this application.
Thanks for letting us know! Happy it worked out
