<div id="assembly"><h2>Assembly instructions</h2>
<h3>Assemble Small extruder gear</h3>
<p>Things needed:</p>
<ul>
<li>1x M3 nut</li>
<li>1x M3 grub screw</li>
</ul>
<p>Steps:</p>
<ol>
<li>Insert nut into cavity in printed gear.</li>
<li>Tighten the grub screw a bit, just to hold in place.</li>
</ol>
<h3>Assemble M8 hobbed bolt</h3>
<p>Steps:</p>
<ol>
<li>Use thread cutting bit in electric screwdriver ...</li>
</ol>
<h3>Assemble Large extruder gear</h3>
<p>Things needed:</p>
<ul>
<li>1x <a href="#thing_hobbed-bolt">M8 hobbed bolt</a></li>
</ul>
<p>Steps:</p>
<ol>
<li>Insert hobbed bolt into main hole.</li>
<li>Add some M8 washers from other side, later with their count you adjust position of hobbed part in filament path.</li>
</ol>
<h3>Assemble Extruder Idler</h3>
<p>Things needed:</p>
<ul>
<li>1x 608 skate bearing</li>
<li>1x <a href="#thing_idler-m8-piece">Idler</a></li>
</ul>
<p>Steps:</p>
<ol>
<li>Insert piece of M8 rod into bearing.</li>
<li>Insert 608 bearing with rod into printed idler part.</li>
</ol>
<h3>Assemble Extruder</h3>
<p>Things needed:</p>
<ul>
<li>2x 608 skate bearing</li>
<li>1x <a href="#thing_extruder-body">Extruder body</a></li>
<li>3x M3 10mm screw</li>
<li>2x M4 nut</li>
<li>1x <a href="#thing_small-gear">Small extruder gear</a></li>
<li>1x M3 25mm screw</li>
<li>1x NEMA17 stepper motor</li>
<li>1x <a href="#thing_large-gear">Large extruder gear</a></li>
<li>8x M3 washer</li>
<li>1x M8 washer</li>
<li>1x <a href="#thing_idler">Extruder Idler</a></li>
<li>1x M3 nut</li>
<li>2x M3 40mm screw</li>
<li>2x <a href="#thing_extruder-spring">Extruder spring</a></li>
<li>2x M8 nut</li>
</ul>
<p>Steps:</p>
<ol>
<li>Take idler and insert nut into small nut-trap inside the hinge.</li>
<li>While holding the nut in place, preprare M3x25 bolt with washer and screw it into the hinge just enough to hold the nut.</li>
<li>Now take the extruder body and idler. Place idler on the hinge counterpart and compleately screw the M3x25 bolt. This will create secured hinge.</li>
<li>Place M4 nuts into their nut traps, secure them with piece of tape. We need them in place, since later they would be harder to access.</li>
<li>Prepare your NEMA17 stepper motor and three M3x10 screws with washers.</li>
<li>Hold motor on place and lightly tighten the screws. We need to adjust motor position later, no need to tighten it hard.</li>
<li>Place two skate bearings on ther position, they should snuggly fit in.</li>
<li>Insert prepared large gear into the body with mounted bearings.</li>
<li>Check if the alignment of hobbed part with the filament path. Adjust it accordingly with adding or removing M8 washers.</li>
<li>After adjusting, we need to fix the bolt in. So we place washer at the end of hobbed bolt and with two M8 nuts we will do locknut by tightening them against each other.</li>
<li>Check if large gear turns freely.</li>
<li>Prepare two M3x40 screws with sandwitch of washer-spring-washer.</li>
<li>Insert two M3 nuts into nut traps on top of drive mechanism.<br/><img src="images/extruder/top-nut-traps.png" width="256" /></li>
<li>Insert prepared screws into the holes on idler. Close the idler and tighten the screws into the trapped nuts. More you tighten those screws, more pressure will be on fillament.</li>
<li>Your extruder is done.<br/><img src="images/extruder/assembled.jpg" width="256" /></li>
