Occasionally I want a little bit of smoke in a shot to create atmosphere. Small product shots, Fungus, Flowers etc can be fun with a little smoke. Out in the field it is impractical to use a mains powered smoke machine and the battery powered ones can be very expensive. So the next option is to use a vape device. These can be had for a couple of pounds, are rechargeable and you can make the smoke liquid cheaply at home. My first attempts, being a non smoker, involved using a bulb blower to suck smoke from the vape device into the bulb then squirting it on the subject as required. While this worked, it was a bit fiddly. So I designed the attached device so I can blow in the tube at the side and smoke is emitted at the top. Currently I have a length of standard, clear, aquarium air pump tuning attached so I can have the device where I need the smoke and can gently blow down the tube. It works well and is easy to print. Supports are required only under the inlet tube. The design as it stands will fit many round vape devices with a 21-23mm diameter. I have attached the cad file too so it is easy to adjust the diameter of the wrap to fit other round devices.

My next plan for this is to use a small 5v pump wired so when the vape is activated on a button press, the pump also activates. and blow air into the tube. I have done some tests and have a working prototype but it still needs a bit of work. I am very new to CAD so have a lot to learn. Apologies if the Fusion 360 file is a bit of a mess, this was my first project.
