M8 ptfe coupling for Mini
prusaprinters
<p>Got tired of cheap ptfe quick connecters wearing out and wanted something that would allow the ptfe tube to pass through so its all one piece instead of 3 pieces. It uses two spare screws that come with the mini.</p><p> </p><p>You will need 2x M3 screws at least 20mm in length. The mini comes with a spare 20/40mm screw so I’ve used them. The 20mm screw is screws all the way and with the 40mm screw just make sure you can’t see the threads anymore.</p><p>When threading in the couplings don’t over tighten them. Finger tight will be enough, once the m3 screws are in the couplings won’t loosen or twist out.</p><p> </p><p> </p>
