Lots of fun with a bubble straw that produced 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:

• Resolution: 0.2mm 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.
