thingiverse

<p>This modification allows you to mount the silent <strong>4020 axial fans</strong> on the <strong>Ender 3</strong> 3D printer head: one for the hot-end and one for filament cooling.</p> <p>Round spacers are used to raise the cage above the hot-end so that the 4020 fan can be mounted with 4 pcs M3x20 screws instead of the 4010 fan. Use two M3x14mm screws to mount the cage.</p> <p>The <strong>fan duct</strong> is used to attach an axial 4020 fan instead of a radial 4010 to the side of the cage. Tap the 3 holes for mounting the fan with an M3 tap. Use the default screws for mounting the fan duct to the cage and 3 pcs M3x25 for mounting the 4020 fan.</p> <hr> <ul> <li>no rafts,</li> <li>no supports,</li> <li>0.2 mm layers, 3 top and bottom solid layers, 3 perimeters, at least 20% infill,</li> <li>You need a M3 tap, 4 pcs M3x20 and 3 pcs M3x25 screws.</li> </ul>
