Modified Extruder Body STL for ASA/ABS Printing

prusaprinters

<p>When printing with ABS or ASA, the tendency for the filament to warp can cause failures and sometimes requires extra concessions.</p><p>The extruder body for the MK3S+ is one of these such prints. &nbsp;There are obviously benefits of printing the extruder parts from high temperature materials, but the original design is prone to warping on these same high temperature materials. &nbsp;The PINDA clamp is open on the build plate and as the print progresses, it eventually loops back around and bridges at the top. &nbsp; If the small outside part is off the smallest bit (because it has warped away from the body), the final bridging will fail and the print will therefore fail.<br><br>I added a couple of vertical connectors inside the open part of the PINDA clamp to keep it from warping away from the body as the print progresses. &nbsp; Once the print is complete, use an Xacto knife or similar to simply cut these four bars away so that the clamp is open again.<br><br><strong>PLEASE NOTE: </strong>These four bars are purposely pretty small and they start as a tiny bridge on the second or third layer depending on your slicer settings. &nbsp;Once you slice the STL use the visualization tools in your slicer to take a look around layer 4 or 5 and make sure they will print. &nbsp;Sometimes, thin wall settings or other settings in slicer will omit them. &nbsp;&nbsp;<i>In most cases</i>, this should not happen - but it never hurts to check the GCODE visualization to make sure before you spend the time printing the part :)</p><p>Please post your makes - I would love to see how things turn out for you :) &nbsp;Enjoy!</p>
