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
I did a bunch of vacuum adapters last year and ended up just going for some stiff TPU. Solves the cracking at layer lines issue and compensates for unevenness of the vacuum.
