"Der Skorpion" - Fan Duct for Geeetech A10M and A20M dual colour printers

prusaprinters

<p>Update 29.12.2018:<br/> Version 1.1 of Skorpion where the duct mount was thickened and the duct outlet was shortened to be a little more far away from the heater block</p> <p>Because the cooling on my A10M and A20M was not quite convincing, I designed this part with following concepts in my mind:</p> <ol> <li>More silent 40x10 or 40x20 Fan instead of the two 30mm fans for the hotend</li> <li>Better cooling with a radial 5015 Fan </li> <li>To see better whats printing</li> <li>Customisable</li> <li><p>Good looking<br/> The BLTouch has following X and Y offsets:<br/> X= -38 mm<br/> Y= +10 mm</p> <p>Please consider leaving a TIP if you like it. Thanks in advance.</p> <p>What you'll need:</p> <p>Extra parts:<br/> 1x Axial 40x10 or 40x20 for the hotend<br/> 1x Radial 5015 for the Fan Duct / Part cooling fan<br/> (the A10M and A20M is 24V machine so make sure the fans are 24V)</p> <p>Printed Parts:<br/> 1x Part A+B(left+right mount) + Part C(duct) + Part D(FrontBit) + Part E(BLTouch optional)<br/> 1x recommended Hotend PCB Mount: <a href="https://www.thingiverse.com/thing:3195894">https://www.thingiverse.com/thing:3195894</a></p> <p>Mounting bits:<br/> 4xM3x12 for carriage<br/> 2 M3 screws for carriage<br/> 4xM3x16 for hotend (BLTouch + Fan Duct)<br/> 4xM3x16 for Hotend Fan (for 40x10 fan), and 4xM3x25(for 40x20 fan)</p> <p>All the modifications you make to your printer is your own decision, I cannot be held responsible for damages what may result by this mod.</p> <p>Special thanks for beta testing: Eric Beirnes, Irene Wolters, Jarno de Jong, Johann Podina, Kevin Goethals, Sammie Spencer</p> <p>and David Petsel and Sven Beckum for some of the design ideas.</p> </li> </ol> <h3>Print instructions</h3><h3>Category: 3D Printer Parts Print Settings</h3> <p><strong>Printer Brand:</strong> Prusa</p> <p><strong>Printer:</strong> <a href="http://amzn.to/2rqZ6Uo">Prusa Clone</a></p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> Yes</p> <p><strong>Resolution:</strong> 0.20 mm</p> <p><strong>Infill:</strong> 25%</p> <p><strong>Filament:</strong> fillamentum PLA for mount PETG for Duct<br/> <strong>Notes:</strong></p> <p>Supports needed only for Part A + B + E (Slic3r PE settings in the pictures)</p> <p>Fan duct(C) and front bit (D) doesn't need supports.</p> <h3> Post-Printing</h3> <p><strong>Bought these insulating pad to insulate my hotend for maintaining the temperature. Using this you can even print the fan duct in PLA.</strong></p> <p><strong>Punched a hole in one of them for the nozzle.</strong></p> <p><strong>Wrap it around the bottom, and cut another piece in two to use them on the sides.</strong></p> <p><strong>And mount the final piece and tape the whole thing with kapton heat resistant tape.</strong></p>
