We bought some knock-off bubble juice from the discount store for our cat but the included bubble wand left something to be desired.
The default settings for the parametric file creates a wand with a 1/2-inch radius which is exceptionally large for a bubble wand but also creates very large bubbles. It is recommended that you use an air blower of some kind with larger wands. Setting a smaller radius size (perhaps of 1/4"-3/8"?) for small bubbles which will require less blowing.
WARNING: Please exercise caution when blowing bubbles as it can cause light-headedness, dizziness, nausea, hyperventilation, fainting or falls which could cause injury or even death! This bubble blower comes with no warranty and I accept no responsibility, nor liability for injury caused by unreasonable, overzealous or excessive amounts of bubble blowing.

Be very gentle when pulling this model off the bed. I used PLA which feels very fragile at this thickness. I don't know that a raft is necessary but I use one for nearly everything since my heatbed is somewhat damaged/warped.
If you want to make a smaller wand remix it with the customizer instead of shrinking it in your slicer program.
Overview and Background
Bubbles have unexpected physical properties that can help students at all age ranges to understand various concepts touching on several scientific and engineering fields from physical chemistry to structural engineering and even astrophysics.
Edit: not astrophysics ... I'm thinking of Lagrange, not Laplace.
Lesson Plan and Activity
Lectures on bubble physics: geometry, chemistry, physics, medicine, computer science, engineering and mathematics
Bubbles have incredible potential as a versatile teaching tool for all age ranges from Kindergarten to post-graduate mathematics.
A sphere is the most efficient way to store the largest volume with the smallest surface area. While this is a fairly simple concept on its face the deeper ramifications of this touches on several major scientific fields. Perhaps most fascinating is the use of bubble to solve complex geometrical problems that would be somewhat difficult to solve with mathematics. In this regard masses of bubbles can be considered a form of analog computer. Something as seemingly simple as a mass of bubbles can be used to generate highly efficient tensile roof structures like the West German Pavilion at the 1967 World Expo in Montreal. This is an example of a mathematical modeling technique known as Dynamic Relaxation.
The appearance of the mysterious iridescent sheen on a bubble's owes in part of the physics of the way the various molecules in the soaps, thickeners and water that go into the bubble soap interact. The same is true for various other properties of bubbles such as how long a bubble lasts, how many bubbles can be produced in one breath, how readily a bubble clings to a surface or bounces off it, etc.
The film between two connected bubbles bends into the large bubble because the smaller bubble is under a higher pressure as predicted by the Young-Laplace equation which is a non-linear partial differential equation that has applications in cardiovascular and respiratory physiology.
Who knew bubbles were so amazing? The scope of this is far to broad to be thoroughly covered in a single lecture in any appreciable depth.
