Source for small "potting boxes"??.....

[Smokey]

I'm looking for a good source of small potting boxes.  The kind you put your PCB in and then fill with epoxy to act as both a weather seal and a housing. 
Requirements include some sort of mounting tab to screw the thing down.

Here is an example of the configuration I'm looking for at the moment:


I would think someone would have that off the shelf.  I don't really want to have that custom made right now.
Thoughts?

Winner!  Obviously they are listed as "Negative Ion Generator Modules"!  How the hell did you find that?

Hammond Plastic Potting Boxes 1596 Series
OT I don't know what mould release to use for silicone, if that's the potting compound.

[Smokey]

It will probably be epoxy. No release.  The potting box becomes the outside of the thing.

Searching for potting module case or similar.

They call it "CBB61" which looks like its used for motor capacitors as well, various products.
Can always try to work back from the end product and ask the manufacturer if they are willing to share who they buy the cases from. Depending on how friendly they are.

"CBB61" is chinese regulatory code for a type of film capacitors used in motor start and run. Should be a plastic cylinder?
PS Caution going to the only site explaining CBBxx codes, it has malware.

Yeah maybe that is some other classification, or maybe that is what is potted inside, this is the type: https://www.aliexpress.us/item/3256805487741980.html
Most are "single ear" or less though.

I think this guy is the winner:

The pricing is a little screwy though.  At $0.15 each, and 1000MOQ, that's $150 worth of product.  But they also list $3404.15 for shipping!?

Note:  Looks like they have their own store:

Why not order from a reputable vendor like DigiKey? “Box, potting” is a type of box you can filter for in the Boxes product subcategory.

I would actually very much prefer to order from a "reputable distributor".  That is always my first choose. While I appreciate the link to a digikey category, if you had gone to that link you would see that the box configuration I need isn't available.  And while there are a bunch of pages of products, once you get past the first pages the boxes cost like $10+ each.  If I wanted to spend that much money I'd have something custom injection moulded.
This is compared to a random Chinese seller, but with the thing I actually need and a cost of $0.12.

Lose the bad attitude, dude. Newsflash, I’m not clairvoyant. I have no idea what configuration you need — you posted a screenshot with 38 different sizes.

Meanwhile, your original post made it clear you hadn’t even looked at regular sources, since you didn’t even seem to know if the boxes existed as a standard product, something a cursory google search would have shown.

Hah.  All good.  I can't be in a bad mood in a world where I finally know where to buy "Negative Ion Generator Modules".
