About this 3D model

This adapter was designed to mount a 4010 or 4020 fan in the CNC or laser head. In my laser unit, I replaced the 0.5W laser with an Eleksmaker 2.5W laser and needed sufficient cooling. In addition, the extra fan blows the smoke away from the printer. However, a 12V power supply is needed for the fans. How I soldered these can be seen in the pictures.
