STROODSNOUT

<p>This is the heater barrel for a plastic filament extruder. Designed to take a temperature sensor and up to 2 x standard 3D printing hot end heaters.</p><p>The funnel top is intended for use with a PET drinking bottle screw thread, it's also provided with a fused water cooling attachement to increase the hot and cold differentials to prevent sticking of pellets before they are caught by the auger.</p><p>See STROODSNOUT augerV2 and STROODSNOUT flange2 for the two other parts required.</p><p> </p><p>Lettering serves to increase heat dissipation area at the hopper end but the hot end itself should be insulated thermally.</p><p>Tho output nozzle has a design size orifice of 2.85mm diameter and it's possible to extrude as is after cleaning with a drill bit but the intent is to tap to M6 an inside thread in the covering cowl with an "End tap". A standard nozzle can then be screwed in, preferably with fine metal gauze filter and some teflon thread seal tape.</p><p> </p><p>The relatively short length and volume are intended to reduce motor loading and make stepper motor drive practical. Keep an eye out, I'll be designing a coupler for stepper motor drive option in the near future to go with the STROODSNOUT auger. Otherwise it can be driven with a standard Lithium ion screwdriver socket! For stepper motor drive, 200 step per revolution motors are recommended.</p><p> </p><p>Note that in the images showing the auger and end flange, thse are separate purchases.</p>
