As temperatures rise due to the El Niño effect, Crafterboi has developed a fan-assisted back protector as a solution to sweating caused by backpacks. The open frame printed with PETG provides airflow between the bag and the back, while two 5-volt fans at the top offer cooling. The fact that the prototype is made from a pizza box also draws attention.
Why it matters
The development proposes a different solution to the sweating problem associated with backpack use by addressing air circulation between the bag and the back, rather than focusing solely on fabric or bag design. The combined use of a PETG frame and fans shows that the idea is being considered not as a simple accessory change but as a wearable setup. However, the prototype that began with a pizza box indicates that the work is still at the testing stage; therefore, it remains unclear how the approach will perform under daily-use conditions. The news also makes the technical framework of the design process visible for those who carry backpacks in hot weather, as well as for those interested in low-cost, manufacturable prototypes.
