<p>I received the updated Version of the K40 Laser (Vevor type with digital reading, emergency stop, light). It also had a new exhaust fan assembly, which is screwed directly to the exhaust duct. To fit the motorized lasertable <a href="https://www.thingiverse.com/thing:4066979">https://www.thingiverse.com/thing:4066979</a>, you need a shorter exhaust duct.I didn't want to cut the sheetmetal original so I quickly designed a new one. It can be screwed on as is (thread the M4 screws into the plastic) or you can also use meltin inserts for M4 screws as I did.</p> <p>The exhaust fits on an Ender3 buildplate or anythingthat can handle 200mm width.</p> <p>OpenSCAD file included as usual for easy adaption in case, China changes something on short notice! ;)</p> <p>Enjoy!</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div> <p><strong>Filament:</strong> Noyes PLA aluminium</p> </p></p></p> Category: DIY
