Ender & CR10 Filament Extruder Block with Threaded Coupler and Nut

prusaprinters

<p>The PC4-M6 Coupler that came with my Ender 3 was broken out of the box. The extra that came with the printer only lasted a few prints until it could no longer hold the PTFE tube when printing. I found this genius printable coupler but the threads were so weak that it broke when I was trying to thread it into the extruder block. Thus, this remix.</p> <p>With this block, we no longer need to buy couplers. Just use a wrench to make this tight and the PTFE tube aint goin nowhere. An added bonus is this block is flexible filament friendly. I trimmed my PTFE tube a bit and pushed it through to get it closer to the gear and bearing.</p> <p>I have been printing several months with no issues. Including many 10+ hour prints and several 20 hour prints back to back.</p> <p>Enjoy and post your makes!</p> <h3><em>If you found my Things useful, treat me to a cup of coffee by using the PayPal button below :)</em> Buy me a cup of coffeeBuy me a cup of coffee $3.00 USDBuy me a massive cups of coffee $5.00 USDGive me a caffeine coma $10.00 USD Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p><strong>Printer:</strong></p> <p>Ender 3</p> <p><strong>Rafts:</strong></p> <p>No</p> <p><strong>Supports:</strong></p> <p>Yes</p> <p><strong>Resolution:</strong></p> <p>.1</p> <p><strong>Infill:</strong></p> <p>100</p> <p><strong>Filament:</strong> CTREE PLA Green<br/> <strong>Notes:</strong></p> <p>Print Speed: 40</p> <p>NOTE: Be sure to print this with the threads facing upwards.</p> Category: 3D Printer Parts
