Copperhead + BMG Direct Drive for Ender 3 / CR-10(S) Tank Remix

<p>&lt;UPDATE: I have successfully printed PC+ at 260C for 5+ hrs with no warping of any of the parts. Also the hotend cooling with the 4010 pulling air across the heatsink worked beautifully.</p> <p>I have printed with PLA, PETG, and PC+ and have had no issues with clogging.</p> <p>Retraction settings for my setup are down to .4mm and stringing is non existent, even with PETG.</p> <p>UPDATE&gt;</p> <p>This is a remix of the <a href="https://www.thingiverse.com/thing:3080548"> "Tank" from Greg191134</a> for the Slice Engineering Copperhead hotend.</p> <p>Most parts have been significantly remixed to accommodate the new hotend. Fragility of original design has been resolved.</p> <p>The hotend cooling solution has also been significantly reworked to use the stock Ender-3 4010 part cooling fan in a unique configuration that will exhaust the heat upwards (ala Hemera) as to not create any drafts when printing technical materials. At last this fan has a good use! One corner will need to be clipped to clear backplate bolt.</p> <p>The <a href="https://www.thingiverse.com/thing:4139858">part cooling fan shroud is the same as Scope6666's part</a>, but the bracket has been reworked a little for quality of life improvements. Not sure yet if the fan is aimed perfectly as the Copperhead is a little taller, time will tell.</p> <p>I also beefed up the BL-Touch mount and put in a center hole for pin access. Also included are some shims to help get the BL-Touch height where you like it.</p> <p>Most hardware is the same as the original tank design, with exception of the hotend fan. Stock Creality screws should work here.</p> <p>Tolerances are tight in order to ensure a secure fit, your printer will need to be well adjusted for success here.</p> <p>I would print in PETG (pictured) for best results, but this should work in PLA if your <a href="https://www.prusaprinters.org/prints/32781-slice-engineering-copperhead-silicone-sock-mold">make yourself a silicon sock for the heater block</a>. I used Permatex Ultra Copper silicon and it worked nicely.</p> <h3>Print instructions</h3><p>I would print with 4 perimeters and 4 top/bottom layers for best strength.</p> <p>PETG of "better" filament recommended as PLA might deform (sock highly recommended if going PLA).</p>
