  🫧 Baby Bubble Blowing Box 🫧 Tiny box, many bubbles, endless joy! Do you also have a forgotten 5V axial fan in your workshop? Turn it into a whimsical bubble-blowing machine with this compact and clever print! The Baby Bubble Blowing Box is a 50×50×50 mm bubble toy powered by a small fan (Sunon EE40100S 40 x 40 x 10 mm or similar) and a few drops of bubble mix. This model went through many prototypes — airflow, wand geometry, and soap viscosity all had to work together. The result? A delightfully simple yet mesmerizing bubble maker. that can be used in other toys     🧩 Features:   Fully 3D-printable (except the fan) Works with standard bubble solutions (or your own mix) Overflow spout prevents messy overfilling Includes a mini funnel for easy refills USB-powered (USB-A soldered to the fan)   🛠 Print Instructions:   Use 0.2 mm layer height Material: PETG recommended, but PLA works too Follow the orientation in the included .3mf file You may need to ream the center hole with a 5 mm drill for free wheel rotation Assembly tip : Tweezers help when installing the wand and ring   🧼 Usage Tips:   Fill with 10–15 ml of bubble mix (don’t overfill) The wand size and soap viscosity matter! Designed for axial fans like Sunon EE40100S — other types untested   ❤ If you like it:   Please give it a heart — it’s the only “payment” I ask Post a photo if you print it — I’d love to see your version!
