The New Hotness

  • Makergear M2: MAKE Magazine Torture Test

    This was the second object I printed, immediately after getting that good thinwall box:

    MAKE test object - arch anchor fail
    MAKE test object – arch anchor fail

    The arch foot broke loose from the platform after it grew to about 8 mm, but that seems to happen with most of the DIY printers. Apart from the tangle produced by that flaw, the rest of the object came out essentially perfect:

    M2 - MAKE Magazine Torture Test - box and pillars
    M2 – MAKE Magazine Torture Test – box and pillars

    The surface finish is rougher than I think it should be, but the dense zigzag infill on the two thicker solid walls of the box seems to disturb their outer finish; the two thinner walls have linear fill and are fine.

    There’s no source code, as I used the original STL from Thingiverse.
