Mini Router Table Dust Collection Hood

This mini dust-collection hood is for a router table insert with a 35 mm hole for router bits with bearings like flush-trim or round-over bits. That allows for good dust collection while most of the router table is empty and no fence is in the way. It's designed for an insert-thickness of 9 mm. However, I included a .step file to modify the part quickly.
In this video, I briefly show the usage of some parts:
