Summary

Design a DIY blower using a 12-volt RS 775 motor.
All the parts used in the design were made by the Ender-3 3D printer.
Assemble the motor and the motor bracket using two M2 screws.
Apply a slight force to the impeller to install it on the motor shaft.
Assemble the motor bracket and housing using four M2 screws.

When a 12-volt, 2-amp power supply is applied, it works very well and can blow away all the dust.

About assembly

When assembling, you need some M2 bolts and nuts to connect the housing, and you also need two M3x5 bolts for the motor bracket. The motor bracket and impeller will be made by 3D printing. You need a motor, a pipe, and some small nuts for assembly.

How I designed it

Designed using Fusion360 and 3D-printed with an Ender-3.
