2" (50 mm) Blast Gate

I remixed this Blast Gate for use with the 2" (50 mm) pipe that is used in home built in vacuum installations. I plan to use it in a dust collection system for my small shop. I don't have any need for a giant system with 4" pipe as I will just be using it on my CNC and a couple of small tools. (I do have a 100 mm size also - see my other designs) The 2" pipe is available at most hardware stores, is reasonably priced and there are a good assortment of fittings available for it.

I included the locking holes in the shell, although the fit is quite tight in the shell, so I don't think I will need them, but they are there if you do.

The .step files are also included if you would like to make any changes.

Edit:
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 fine.
