Duct Collector Quick Connect

I made a quick connect dust collection system using a toggle latch.
The latch is attached with two 3mm screw.

I'm also opening the design on onshape, I created it for 2.5 in hoses, but you should be able to change the variables to fit your hose and tools:

there are 3 main settings to change:

hose_internal_diameter: set to 65 mm for 2.5 in hoses, change to fit your

tool_port_external_diamter: to match your tool (set to 65 for my table saw), change to fit the port in your tool

overlap: how much is the overlap between the hose and tool adapters, 19mm works well for 2.5 inch hoses, but might need to increase for 4 in hoses.

I included adapters for the tools I have.

if you have a custom tool port, like the hvac shop or the jointer with the extra holes, I created a base for custom connectors, you should just need a loft, extrude and shell to start.
