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

    • There are variations to support other options like Beta heatsink, MMU2, etc. Search for Skelestruder on Thingiverse.

    • 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.
