This guide will step you through the process to build and install the best extruder for your Original Prusa i3 MK3 printer.

    • Get the printable parts for the basic Skelestruder from here: Skelestruder

    • There are variations to support other options like Beta heatsink, MMU2, etc. See collection on Thingiverse.

    • Skelestruder needs a few HW bits (vitamins) that are harvested from your stock MK3 extruder. See HW Table for list of required and optional parts to acquire, along with example links.

    • Important: before you start printing parts, please calibrate your extrusion using this or similar tester. Most of the parts of the skelestruder are 3D printed. One of the nice features is there are considerable options, in terms of colors and material choices allowing you to customize the look and feel.

    • Parts are designed to minimize unique slicer settings, changing orientation, and post-processing. Ideally just print and go. That said, some post-print dressing is helpful. Before starting, clean up parts where they interface, such as removing burrs and blobs.
