The New Hotness

  • Smashed Glass Work Palette

    Having a myriad small glass fragments and an idea for their use created the problems of organizing the pieces while not losing them under the bench.

    As with the shattered shot-glass coaster, start by lining up the suspects on the scanner:

    Small fragments
    Small fragments

    Blow out the contrast, flip right-to-left, then mask them en masse:

    Small fragments - masked
    Small fragments – masked

    Delete the images (inside their selection masks) to create a binary mask:

    Small fragments - masks
    Small fragments – masks

    Have LightBurn trace the binary images, wrap a rounded rectangle around the lot of them, duplicate the rectangle as a base plate, then fire the laser:

    Smashed glass palette - fresh cut
    Smashed glass palette – fresh cut

    They’re not secured in their sockets, but they won’t fall out unless I fat-finger the whole affair:

    Smashed glass palette - loaded
    Smashed glass palette – loaded

    The thing that takes getting used to: the whole process was about two hours of wall clock time from start to finish, with a leisurely breakfast and KP in the middle.
