A blast gate to insert into a 4" flex hose. This is a great and simple design that works well. Found on Thingiverse, the designer was kind enough to include the fusion files. This makes it possible to make any changes.
the main parts ust the entire bed of my Mini.
I printed two of the male parts, currently printing the slide. fingers crossed.

with the help of forum folks, i finall got this to print
using Overture filament.
It was necessary to slow the speed to 60 first layer then 75
raise the heat bed to 75.
Not sure what else to include. I had many fails, but I am convinced these were caused by my inexperience.
