Lots of fun with a bubble straw that produces a ton of bubbles for the kids.
Use: Make sure the tip of the straw is submerged in the bubble solution for best performance. See the photo with the red line.

I've included the .3MF that uses the default Prusa slicer setting on MK3s for 0.3mm in PLA. Print settings are listed below.
Filename:
- 1 x BubbleBlowStrawToy.stl
- 1 x BubbleBlowStrawToy_Solution_Container_Optional.stl (Optional Print)
Print Settings:
- Printer: PRUSA MK3S
- Resolution: 0.3mm Layer Height (0.4mm Nozzle)
- Filament: PLA
- Supports: No
- Raft: 3 Raft layers are recommended to hold the print in place.
- Note: I didn't want to use a brim on the feet as would be difficult to clean up. I found the raft was the best option.

Update: 05/13/22
- Added an experimental model, and added more fins to help produce more little bubbles.
- Experimental_MoreFins_BubbleBlowStrawToy_Without_Handle_v1.stl

Update: 02/11/22
- Added BubbleBlowStrawToy_V2.stl, which adds a handle and mouthpiece. Print orientation changed, brim or raft can be used. Looks more like a horn.
- Added BubbleBlowStrawToy_v2_Without_Handle.stl, which adds the mouthpiece.

Attached is the video below of my daughter testing out the bubble straw.
