<p>I saw <a rel="nofollow" target="_blank" href="http://www.thingiverse.com/whpthomas/designs">http://www.thingiverse.com/whpthomas/designs</a> design of upgrade extuder head, and since I had problems with this, I made a derived a new design that fitted my Replicator 1 Dual.<br>Using a spring that we have at work its partNo 1180 and should be avalible as a spare part for Poseidon diving equipment.</p><p>It is also made for the dual extruder thats why it is sticking out upwards instead of on the sides, and the adjustment screw is inside the handle.</p><p>I made the pressure of the spring adjustable so that it would be easier to get the best result out of the print, and I have printed for 980 h without any feed failures since I made the upgrade.</p><p>I got the original solidwork files of the whole Replicator from<br><a rel="nofollow" target="_blank" href="http://www.thingiverse.com/tlalexander/designs">http://www.thingiverse.com/tlalexander/designs</a><br>Which made the design work easier.</p><p>I got myself another printer, Replicator 2x, got it cheap because the previus owner had problems with it.<br>So I made a new base that will fit the 2X, with attachment for filament hoses, the other parts is the same.</p><p>You can follow the instructions of whpthomas, will work for this version also.<br></p><p>I printed the new part with<br>Standard mode<br>0,1 mm<br>4 shells<br>99 % infill</p>
