<p>I have a Prusa clone 3D printer (that use the MK2 extruder model) and after some time the screws holding the hotend fan become loose since they were screw directly on the plastic cover and body of the struder.<br/> The two front fan screws hold the capacitive sensor so I understand that those two loose screws were affecting the Z high reading.</p> <p>So I decided to make a modification of the original Prusa MK2 extruder cover and body to include some M3n nuts to hold the Hot End fan and the Fan Nozzle piece in place avoiding the M3x14 screws being screwed directly to the plastic material.</p> <p>Parts should be printed in PETG with 0,2mm layers with 20% infill.</p> <h3>Print instructions</h3><h3>Category: 3D Printer Extruders Summary</h3> <p>I have a Prusa clone 3D printer and after some time the screws holding the hotend fan become loose since they were screw directly on the plastic cover and body of the struder.<br/> The two front fan screws hold the capacitive sensor so I understand that those two loose screws were affecting the Z high reading.</p> <p>So I decided to make a modification of the original Prusa MK2 extruder cover and body to include some M3n nuts to hold the Hot End fan and the Fan Nozzle piece in place avoiding the M3x14 screws being screwed directly to the plastic material.</p> <p>Parts should be printed in PETG with 0,2mm layers with 20% infill.</p> <h3> Print Settings</h3> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> 0,2</p> <p><strong>Infill:</strong> 20%</p> <p><strong>Filament:</strong> <a href="https://www.printalot.com.ar/filamentos/petg/"> PrintaLot PETG </a></p>
