Description
MacBook Air boasts exceptional performance, but lacks active cooling, prompting the creation of this Type-C powered, 5V fan-driven vertical stand. With the fan engaged, gaming performance is significantly enhanced!
The design features a sleek, matte white finish. Its compact size, simple circuitry, and quiet operation are noteworthy. It accommodates both cased and uncased devices, maintaining stability and delivering superior cooling—a rarity in the market! External component costs are under 10 yuan, representing excellent value.
Parts List:
Bambu PLA Lite official filament
Type-C female receptacle with ears + pair of M2 screws (0.5 yuan)
5V 2-wire 8010 fan (5 yuan)
Push-button switch, SMTS-202 dual-inline six-pin (other specifications are acceptable substitutes if you have them on hand)
Pair of 3mm self-tapping screws (for securing the fan cover; alternatively, use strong adhesive!)
The Type-C receptacle can be mounted externally or internally. Pre-test your data cable's connector length and protective sleeve thickness to ensure proper insertion. I opted for external mounting due to my inexpensive cable's oversized connector.
Power supply requires a USB-A power adapter (inexpensive options are readily available), as the receptacle board may not recognize the power protocol otherwise. Higher-quality receptacles are available as alternatives if desired, though I did not utilize one.
The A1 mini was printed in two parts to minimize support material usage. The top fan frame was designed as sacrificial support, facilitating easy removal. Slight wobbling occurs at approximately 40mm print height, but this does not affect functionality and prevents collapse of the main frame. If concerned, a reinforcing crossbeam or tree-like support structure could be added.
The base utilizes minimal tree support; exercise caution during removal to avoid damaging the receptacle holes. Small support structures within the wiring channels should be removed using needle-nose pliers.
The two base covers are designed for a tight fit; refine the locating lugs to ensure proper seating. I opted to forgo this step, haha.
Applying anti-slip rubber pads to the base will improve stability.
PS:
PWM speed control was initially considered, but the fan's remarkable quietness rendered this unnecessary, resulting in a simpler, more aesthetically pleasing design.
Users lacking soldering skills can purchase pre-wired components for a minimal added cost and assemble manually.
