Product Details

Collapsible Sections with Rounded Corners

Due to shipping limitations, the Cloud® is only available to ship to the US, UK, and select EU destinations but more countries will be available soon!

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!

The Cloud® has 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!

Rated as a Class A, B, C, E, and F fire extinguisher, the Cloud® will only activate with direct contact with a flame for at least 3 seconds and will not trigger due to ambient temperature or smoke. Once activated, it makes a brief explosion, launching a cloud of ABC extinguishing powder around the device. The powder quickly extinguishes almost any fire within its perimeter.

Included:
  • 1 Cloud® Personal Printer Sentry backed with loop material
  • 1 patch of hook material backed with 3M adhesive to mount to wall, structure, or 3D printed holder
  • Wear eye protection and use caution when around a live flame as the explosion is powerful and can launch the powder and film with force.
  • The powder may reach circuit boards, potentially damaging or ruining equipment. It’s strongly recommended to service your machine and consider replacing electronics immediately after extinguishing.
  • This device is to be used only to extinguish fire.
  • Store at room temperature, in a dry, ventilated environment.
  • Do not open the product, disassemble it, or tear off the protective wrap.
  • We did stress testing, and the Cloud® will resist up to 120°C constant ambient temperature.
  • It will never explode without flame, but at 130° we started to have the Shrink Wrap body sag and fail.
  • Any printer with electronics inside the enclosure should never have an ambient temperature exceeding 50-60°C for the function and well being of the electronics, stepper motors, and PCBs.
  1. Attach the Bottom Loop to the wall, printable mounting plate, or the interior of the HotBox® using the provided hook patch.
  2. Position it centered above the primary active machine area.
  3. Mount above the area to protect, directly above the fire risk zone.
  4. Will protect an area approximately 80 cm x 80 cm x 80 cm.
  5. Do not open the product, nor tear off plastic wrap.

Watch our introduction video on the Cloud®:


  • In the event of a fire, the product will release extinguishing powder across the declared area within 3-5 seconds of contact with flames.
  • Be careful during activation as there is a brief powerful explosion and powder dispersion. Wear eye protection and keep your distance when flames are present.
  • The extinguishing powder is non-toxic and can be cleaned by vacuuming after the fire; however, it’s always safer to wear eye protection, a mask, and possibly gloves during cleaning.
  • The powder may reach circuit boards, potentially damaging or ruining equipment. It’s strongly recommended to service your machine and consider replacing electronics immediately after extinguishing.

A1 Top Mount Designed and Installed

Second Cloud installed now. Had to design a mount for it (https://makerworld.com/en/models/645754), which you can download and print your own.

First Of Five - Installed!

After a nearly disastrous fire with one of my printers, I ordered up a handful of these magic pucks. First one installed on my nearly 11 year old, massively upgraded TAZ 4 printer. Three more to go and the fifth is for the printer I purchased for my child as a gift (not yet given).

More to come...

Excellent

Quick delivery, well packaged. This item is compact, easy to install and gives me some peace of mind about running my machines when I'm out of the room.
