A Handheld Fan designed for long and everlasting battery life, smooth airflow, and Compact Ergonomic design ready to accompany you in hot wheather.

1. Position the fan so that you see the side with the fan blade furthest away from you.
2. Turn the knob all the way to the left
3. Press the button for 1 second
4. Slowly turn the knob to the right to adjust the wind speed
5. When you're done using, or that the device turned off, charge the device with a USB C cable, you can use your phone charger if it supports USB C
6. When it is charging, the LED indicator will turn red, when the battery is full, it will turn blue and will automatically stop charging

• It is designed with a shroud
• You can adjust the speed with a knob, allowing for smooth speed control suited for any situations
• It has an integrated battery protection system, preventing thermal runaways when an electrical error occured, and ensuring the batteries are not overcharged, and preventing the battery to reach 0% fully, as it can permanently damage the batteries
• Uses 2 Litium Ion batteries for higher energy density, safer discharge, and longer cycle life than Li-Po batteries
• The motor is a Brushless DC motor, allowing it to run faster, consumes lower power, and can operate comfortable for hours without overheating

ASA or ABS or stronger.

• Body (duct and handle): 0.1-0.2mm layer height, 0.4mm nozzle, 40% infill, WHITE.
• Knob: 20% infill BLACK.
• Fan Blade: 100% infill 0.1-0.15mm layer height, NEEDS HIGH PRECISION, QUALITY, AND STRENGHT (dw it's only 5cm cubic) BLACK.

To be honest, it all started in 2025 of december when I see these overpriced handheld fans on online shops, and wanted to compete with them, then I bought a 15krpm rs280, and tested it with a toy fan blade, it was blowing my hair, so I thought: "why not make a cheaper one than theirs, but have better stuffs?" and then I go to Blender and made it, I wasted my time, I discovered that DC motors sucks at long term use, so i abandoned the project, then I have an idea to make it using a PC axial fan, I did make it with my own money, I got discounted, I used it to chill in class, then I wanted to make a cleaner version, using those 100krpm edf turbo jet fan or something, those are inrunners, and... I figured out those aren't the best, cuz I know that it's impractical to have like 15 mins of runtime on 2 batteries..., so I made this! I calculated the rpm, tip speed, diameter, pitch, trying out fusion, trying out "parametric fan blade generator", then I dumped the generator, so I modified a pc fan blade design, and fit it into the motor (according to the motor desc), I made all of the stuffs (duct, handle, stator blades, etc) all without a reference, only a glimpse of what I imagined it would be like, so now I'm here, I really hope this would be my milestone in engineering, since I started making electronics in late october 2025, and I just discovered Hack Club back in December from an Instagram reel..
