At the heart of this project is the common everyday plastic pill bottle. You'll want to choose one that just fits over your Shop-Vac hose and that you get on a regular basis. This will provide you with many caps that will fit on the bottle so you can make several different attachments that can be quickly interchanged.
I chose to use a lamp nipple for a similar reason. Not only will it make a great small diameter tube for vacuuming, but you can screw things to it to create more attachments.
So now that I've given the rationale for the materials, here is the complete materials list:
- 1 pill bottle with lid
- 1 lamp nipple
- 2 lamp nuts
- E-6000 glue
- 2 cork or rubber pads (optional and not pictured in this step)
