4" to 2" Vacuum Hose Adapter
thingiverse
I designed this to convert my standard vacuum cleaner hose to my Jointer sawdust outlet. It's a 4" to 2" adapter, easy enough to modify for any size hose. I use my shop vac with cyclone dust separator to clean up sawdust from all my woodworking machines. This one has been a challenge as it lacks the standard 2" fitting (my miter saw is next). I printed this in PLA and it took about four hours, but I didn't have to monitor it. The holes at each end are tapered for flexibility with manufacturing variations.
