Air Raid Siren - modified stronger version

prusaprinters

<p>I printed the air raid siren version 2 and ran into some problems when I built it, so I made some modifications to make the siren more durable.</p> <p>Slicing with a slicer that can print multiple models at once with different infill settings is pretty much required. I used simplify3d.</p> <p><strong>To build this you need these metric [mm] bearings:</strong><br/> (amount x outer diameter / inner diameter / height - model#)</p> <p>1 x 47/25/12 - SKF 6005-2Z<br/> 4 x 16/5/5 - SKF 625-2Z</p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>PowerSpec</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>PowerSpec 3D Pro</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>0.2mm</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div></p> <p><strong>Notes:</strong></p> <p>print everything at 0.2mm and 20% infill with the exceptions noted below:</p> <ol> <li>print<strong>SirHa_Gehause1</strong> or the split version<strong>SirHa_Gehause1handle</strong> /<strong>SirHa_Gehause1klein</strong> 3.<strong>SirHa_Gehause2</strong> has built in supports, print without support</li> <li>print<strong>SirHa_Gehause3</strong> or the split version for dual extrusion 7.<strong>SirHa_GetrRad1</strong> has been broken into 3 parts: hub, spokes, and teeth. print the hub and teeth solid 100% infill, and the spokes 20%</li> <li>SirHa_GetrRad2A and SirHa_GetrRad3 have been combined into<strong>SirHa_GetrRad23</strong>, then split into hub, spokes, and teeth. print the hub and teeth solid 100% infill, and the spokes 20% 11.<strong>SirHa_GetrRad2B</strong> goes in the bottom of SirHa_GetrRad23. print this solid. 13.<strong>SirHa_GetrRad4A</strong> and<strong>SirHa_GetrRad4B</strong> both should be printed solid.</li> <li>print<strong>SirHa_Kurbel1_spaced</strong> or the split version<strong>SirHa_Kurbel1</strong> /<strong>SirHa_Kurbel1_spacer</strong>. the spacer keeps the handle tight against the bearing and keeps the first gear and handle in alignment much better. 17.<strong>SirHa_Kurbel2</strong> - print the thread layers and a little into the handle solid</li> <li>print<strong>SirHa_Rotor1_blades</strong> and<strong>SirHa_Rotor1_spindle</strong> together, with blades at 20% infill and spindle solid</li> <li>print<strong>SirHa_Rotor3</strong> at 0.1mm layer height.</li> <li>print 3x<strong>SirHa_Schraube1</strong> and 6x<strong>SirHa_Schraube2</strong>, I printed mine solid and a little undersized (95% scale)</li> <li>the spacer for Kurbel1 makes a huge difference for<strong>SirHa_Schraube3</strong>. I printed it on its side with supports, and solid. This makes the screw a lot stronger in the rotational axis, which is required when using the spacer.</li> </ol> </p></p></p> Category: Mechanical Toys
