Mean Well LRS-350 PSU Cover - Fanless - With logo

<p>Remix that is an easier print;</p> <p>Instead of honeycombs, which are slow to print, I have added alternating lines of 1.2 mm wide, 0.2 mm high.<br/> When printed on 0.1 or 0.2 layer height, the nozzle will have to move only diagonally in 1 direction every layer (0.2) or every 2 layers (0.1).</p> <p>This saves time and filament and because 0.2 layer height is not that much, the resulting grid is surprisingly solid :)</p> <p>Also added the Mean Well logo. Hopefully the letters survive removal from build plate.</p> <p>I print on glass with 3DLac and place it in the fridge after print; I will have no trouble. But if you use a different printed that requires force, however so little, to remove the print from the bed, then the letters will probably break off.</p> <p>I intend to print this for my Ender 5 with relocated enclosure and self designed lid, with a 120mm fan, so there will be cooling, just not from the psu's own fan (which is loud)</p> <p>For my Ender 3 I will use a different one with a silent large fan.</p> <h3>Update:</h3> <p>I have re-remixed this design to exact dimensions with extras;<br/> This design fits well, but is 200 mm long.<br/> The original lid is 198 mm long.<br/> The result is that my connector guard doesn't fit very well.<br/> Also I found myself missing the indicators for +/- and Live/Neutral/Ground.</p> <p>Go see it here: <a href="https://www.thingiverse.com/thing:4800781">https://www.thingiverse.com/thing:4800781</a></p> <h3> final note</h3> <p>If you like it, click the like (heart)<br/> If you print it; post a make<br/> If you have suggestions for improvements, questions, any kind of remarks; leave a comment</p> <p>Looking at the download statistics, you guys and gals out there really like this thing :) so, leave a like, a make, a comment.<br/> Much appreciated!</p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 5</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>.2</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>20</p></div><br/> <strong>Filament:</strong><br/> [</p> <h3> REAL PLA ](http://www.amazon.com/s?url=search-alias&amp;field-keywords=REAL+PLA&amp;tag=thingiverse09-20) Orange V1 tests</h3> <p>After printing it looks great! but in closeup, the imperfections show.<br/> I guess Cura refused to slice the thin parts properly, but since it will (in my case) be behind a cover, I'm not going to bother reprinting.</p> <p><p class="detail-image"><img src="https://cdn.thingiverse.com/assets/b6/41/33/d0/2e/v1\_printed.jpeg"/></p> <p class="detail-image"><img src="https://cdn.thingiverse.com/assets/c2/c4/9e/e2/06/the\_logo.jpeg"/></p> <p class="detail-image"><img src="https://cdn.thingiverse.com/assets/fc/4d/5d/8a/53/v1\_mounted.jpeg"/></p> <div><p>Test prints!</p> I dry-ran a print with the stock fan and cover.<br/> The print is an XYZ cube and during the 45 minute print, the fan comes on 9 times for 2 minutes.<br/> Tested the same print with a 12mm thin 120mm fan, and half open cover (other project for/on my ender 3) the fan also comes on, but very briefly.</div></p> <p> Ender 5 test 1:<br/> a 2nd 12 volt 120x12 mm fan extracting air next to the already mounted 120 mm inlet fan. This should simulate the positive air pressure.<br/> In my Ender 5, the fans run at 6.5 volts, so effectively, this test is with a single fan-ISH, it's not rocket science so it doesn't have to be exact :)</p> <p>I kept the original fan connected.<br/> during the test, the fan did NOT come on, not even once, not even briefly. (I wondered if I had connected it properly, I had :P )</p> <p>Ender 5 test 2:<br/> Removed the 2nd 120 mm fan extracting and kept only my regular inlet fan, still running at 6.5 volt</p> <p>Again, I kept the original fan connected.<br/> During this test, once again, the fan did NOT come on.</p> <p>But to be absolutely certain, I will be running the printer with the original fan mounted as exhaust fan, controlled by the PSU.<br/> If I hear it during prints, I know I will have to ramp up the voltage on the inlet fan a bit.</p> <p>My plan is to go with .5 volts increment until I can run day-long prints with just the single fan, if possible.</p> </p></p></p> Category: 3D Printer Parts
