the Cloud is a personal extinguishing device for any 3d printer, laser, or CNC that gives you peace of mind when leaving your machines unattended for hours at a time!

the Cloud comes with a hook patch on the rear side and a matching separate loop patch with a strong 3M backing. You can mount this loop patch to a wall, your printer, or to a 3D printed bracket to mount to your printer in an optimal position. Plus our most recent HotBox and HotBox Mega have a loop patch already sewn into the inner top panel to give a convenient mounting point!

    Beruhigend zu haben und wird hoffentlich nie gebraucht

    Top Erfindung!! Gerade für Drucke über Nacht genau das richtige damit man ruhig schlafen kann.
    Leicht anzubringen und genau wie beschrieben. Ich hoffe ich werde es nie brauchen.


    Great, as always! I will definitely be ordering more as my business grows!

    Ease of Mind

    Having the cloud watching over my printer gives me that extra ease of mind during long prints that can't be watched over personally.

    Hope I never get to test it...

    This shipped so fast! And I absolutely want to give a huge THANK YOU for including a Thank You Ma'am sticker! I know printing 2 versions affects overhead cost. Be assured the effort has made you at least one fan!!

    Best thing I’ve never used.

    It looks great, it showed up quickly, could be filled with glitter and baby powder for all I know. I hope I never have to use it, but if I do, I’ll come back and let you know how it turned out.
