Vòi Xoay Luồng Khí Vacmaster

Tha Vacmaster is an awesome and affordable bike fan, but the main issue is that the air flow is delivered as a horizontal stream not reaching full cyclist's body. This nozzle rotates the air stream to a vertical one which significantly improves air delivery. Compared to gadgets that rotate the whole fan, this solution retains the practical rotation adjustment provided by the fan itself. 

No support is needed for printing. 

Place a credit card between the nozzle and the fan to get the nozzle frame over the output nozzle of the fan.
