2" (50 mm) Blast Gate

thingiverse

I created this Blast Gate for use with the 2" (50 mm) pipe that's commonly used in home-built vacuum installations. My plan is to utilize it in a dust collection system for my small workshop, as I don't require a massive system with 4" pipe. The 2" pipe is readily available at most hardware stores, reasonably priced, and has an assortment of fittings available. I included the locking holes in the shell, although the fit is quite tight within the shell, so I doubt I'll need them; however, they're there if you do. The .step files are also included for anyone who'd like to make changes. Edit: I tightened up the holes a bit to keep parts better aligned and added a printed set screw as I wasn't fond of the bolt. Set screws can be found on Amazon or eBay, but this works just fine.
