Everything, including YouTube video, shows unfolding throwing on and away you go. Maybe print some accessories for fans, etc. quick mention of having to change the filament feed but zero instructions and I can’t even find the file to print. This thing is not what it’s supposed to be. I guess I’ll have to count this $$ spent as a loss and buy the Bambu enclosure. Very frustrating.

However, it sounds like you are also having other problems and we can assist so you do not have to be frustrated. Please reach out to our helpful technical support team at technical@whambamsystems.com and they would be happy to get your issues resolved.
This thing arrived fast and is a great addition to my printer. I am able to now print in my cold work space without my prints peeling from the bed.
I want to mention that not only is the hotbox a great product, Wham Bam customer service is top notch and they go above and beyond what you would expect. They took the time to custom make a part for my hotbox to fit my specific need. Great product and out of the world customer service.
While this is for the P1P, they said it would "work" for the P1S. And while it does, I whish there were some considerations for a P1P or P1S with an enclosure and a door. Maybe even matching notches on the top that mirror the top for a cabinet like in my pic. I do like it, but whish it were a little better to accommodate both the P1P and P1S.
My unit came with damage when it was delivered and took a little longer than expected to get delivered. The zipper and fabric at the top of the enclosure was not correctly and so with repeated use of that zipper it will likely tear all the way in the future. I do like the design of the front door and the side opening on the unit. All of the openings still align where they should.
Got the enclosure a month ago and have been printing ABS parts like a madman lol. It fits nicely on my bench and even has room for a light fixture that mounts on the top bar. I haven't had a single overheating problem and am very happy with this enclosure!! I would recommend it to anyone with the same machine as me!
Fast delivery. Excellent customer service. I have 2 of these. Both well made with multiple options for access, routing of filament, and quality zippers that actually work.
I was worried that the HotBox V2 would be too small for the Prusa MK3S+. I took a leap of faith and ordered one. It fits great!
I am deducting one star for two issues:
1) the stitching on one of four elastic retainers came almost completely undone when I inserted one of the LED bars inside. I chose to sew it back together instead of returning the unit.
2) the Wham Bam logos are so large and repetitive. I had to cover up the largest with a piece of black duct tape.
I thought it was a fully enclosed unit and there was no bottom, i feel like the fumes escape through there. I feel at this point like i should have just built my own box. Anyways thanks for the product and i guess I'll ask lots of questions next time
I have been wanting to replace my home made enclosure for my Prusa MK3S+ with a high quality, professional looking enclosure for a long time. I also wanted an enclosure that I could easily setup and remove as needed. This Wham Bam enclosure checks all the boxes! It’s thoughtfully designed, well made, and looks great. Added bonus: the black and orange color scheme goes perfectly with my Prusa!
These are definitely higher quality than most, I have a ender 3 neo max and I was printing asa which benefits from an enclosure but I didn’t want it up all the time as my desk is in plan view in a mud room. I find myself wishing there was a middle ground from the small and large that would fit my printer better but there are not many options. Got the laser window with it because I do have a laser engraver too that this doubles with. Worth the sale price but would love a middle sized instead. It’s just too large for a regular desk.
A must for the P1P! Dramatically improved the quality and stability of my prints. Plus, tool storage!
Very quite fits perfect great quality
My prints are coming out nicer. Easier to control temperatures. Should have bought this earlier!
I needed an enclosure for my Prusa MK4 to print some parts in ASA. The case is quickly set up and does the job. After printing with ASA I can take the enclosure quickly away and store it in the compact package it was delivered.
The enclosure does exactly what it is supposed to do.
I bought the enclosure and it just doesn't fit very well. There's no place for the filament to come inside the box, so you have to 3D print a few things, and I did, that just don't work. I think it's an incomplete product that doesn't work as designed. I watched videos on YouTube and with each "solution" to this obvious problem came more problems. This thing just sits on a shelf now for me.

P1P HotBox - 3D Printer Enclosure
I really like it. It's all very nice with a lot of storage on the side and all of that, but the one minus I found is that the door (on my model) isn't closing all the way up because the magnetic tape isn't all around the door. So, when I print ABS or ASA, the smell comes out of the printer, so I have to go to the printer and push all around the door a bit better to make sure it's all the way closed. As for the aesthetics, it looks nice but it is a bit on the bulky side, which is understandable because it is a case for the printer, not a panel. So far, very happy with my purchase.
it does not fit p1p its ok on the sides but the back does not fit at all unless i cut out the holes to make it fit, maybe you sent me one to fit on other machine but this one absolutely does not fit waste of money, I will not recommend it to any body
The box is easy to setup but the window clear part looked like it was used previously, marks and scratches on it.
The Prusa mk3s doesn’t quite fit in the box because of the reel holder on the top and the slit on the top of the box does not line up with where I need i5 to be so 8 will need to come up with another way to setup the spools so I can use the box.
Several of the holes don't line up. I bought 2 of them for my 2 P1P units. Haven't installed the second one because when you open the front it literally tears and has torn the LCD screen from my device and it will never be the same or go back to where it was.
I have purchased 3 Wham Bam hot boxes for my Prusa printers. The first one which I have had for approximately 2 years, has started to come apart near the front left corner. It also had some kind of glue splatters on the viewing window right out of the box. It took several days of cleaning/scrubbing with Goo-Gone to remove most of it.
One unit has a black Velcro patch in the front, top underside, (for your fire suppression device) where on the other two units, this patch is missing. It would have been nice to have it on the other 2.
I do see some minor inconsistencies like the location of the LED light elastic bands on the inside front panel from unit to unit.
Despite the items listed above, they do function as advertised. This is my totally honest review of your product.
Would I buy another unit? Yes I would. They are the best unit in its class.
I have done a couple of Asa prints so far and this hot box made printing Asa so much easier. Chamber temp got up to 40 degrees C. The ease of removal is also something that I think is a plus. Only thing I don’t like is the top piece the supports the ams doesn’t seem to extend to the edges of the printer so one edges hangs a little lower than the other.
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. 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?
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.
