The HotBox is made of high-grade Nylon 600D fabric with fire-resistant coating and lined with a metallic heat-deflecting internal liner that sandwiches around a strong, lightweight honeycomb insulating structure.

The front panel has a large clear window for maximum visibility and easily lifts up for full access to your printer. A velcro retaining strip is on top to keep the panel open while working.

  • Lightweight semi-rigid construction
  • Excellent insulating properties
  • 3 cable exits, one each on the left, right, and back panels
  • A large, transparent front window
  • Large opening for front access
  • Door for pass-through top-mounted spool holder

  • Built-in thermometer (two LR44 batteries not included)

It's good

It's good, really helped me print ABS and ASA. The panels feel high quality and the included temperature sensor is a nice touch.

My one criticism is the zips don't feel massively sturdy, so I would avoid it if you going to be taking this apart and putting it back together a lot. I can't see any complaints online, so maybe it's not an issue.

Something to look into for a V2 WhamBam.

I have 6 of these.

I have 6 of these. They’re the best option for 3D printer enclosures. I have 3 acrylic enclosures from another company, and while I like how rigid and clear they are, they were just not worth the $300 and 3 hours of assembly. These Wham Bam hot boxes are so much cheaper and “assemble” in 10 seconds. Plus I’m pretty sure they do a better job of trapping heat anyways. And isn’t that the point of a printer enclosure?

Excellent Product

The is a great enclosure. It's well made, has plenty of cut for passing through filaments and cables. Best of all, it collapses down so it can be stored away when not needed.

Great enclosure! Great versatility!

8/3/2023 Update: I received my Prusa MMU3 and set it up inside the hotbox. It's a little tight but it all works! My main complaint is that I wish there was a bigger velcro door on top to be able to access the MMU. The 2 little doors only allow for peeking at half of the top of the MMU. Maybe WhamBham can implement this feature in the future.

I was looking for a "bug out" enclosure so I could quickly and without hassle, grab the printer and enclosure and go. This met those needs perfectly. It folds up pretty flat and isn't heavy. Unplug a few cables from the printer, pull the printer and phone out, unzip the whambam and pack it up! The WhamBam hotbox was the only real option that I found that met this criteria. It holds heat well. Printing ASA, I've measured the enclosure getting up to a max of 43c. It seems to have ports/cutouts everywhere you could possibly need them. My only complaint is I wish the thermostat was on the front instead of the top but I have one inside anyway so I can view via octoprint. I plan on adding an MMU to this setup so we'll see how it fits and functions.
