Where can I get the right electronics case?

Question

Do it yourself

Good afternoon!
I'm building sensors based on ESP8266 , i.e. the board itself + sensor + battery ( preliminary dimensions of the final "sandwich" come out 80/40/30 mm ). Over time, there will be a question with the body, so I'm interested in advance. An ordinary plastic box for wall mounting like this ( as an example ) suits me.
The question is, are there stores where you can specify the required XYZ-dimensions of the box before ordering up to a millimeter ( when ordering small lots up to 1,000 pieces )? Or will it be easier and cheaper to finish ready-made boxes for yourself?
Thank you.

Answer 1

Everyone has their own path and preferences. For me, it’s more efficient (and most importantly more interesting) to buy an inexpensive (up to $ 200) laser cutting machine and make cases of any shape, size and beauty yourself ... In addition, it can be used to apply all sorts of inscriptions, make holes, etc.
... a cheap option, buy a cable box of the right size and cut the boxes out of it with an ordinary hacksaw, and the sides are made of plastic building corners. And if you coat it with colored epoxy and glitter on the outside, and then sand it, you will get a designer box in general!

Plastic sheet materials can be cut or molded under temperature. Almost all of these operations are done even by small organizations specializing in the production of advertising.
1. Plexiglas (acrylic) can be perfectly laser cut and glued. If you don’t feel like gluing, then you can cut out small protrusions, which allows you to fix the parts “into the groove”. Something like this did a virtual reality helmet - https://bitbucket.org/Bangybug/vr/src/153768582281... Plexiglas is quite fragile.
2. Monolithic polycarbonate. The laser does not cut, it must be milled. With a jigsaw with a saw blade for metal, you can also make an even cut with little experience. The structure is almost impossible to break. It is necessary to choose such speed at which the polycarbonate does not begin to melt.
3. Temperature forming can be used instead of cutting/milling. Suitable for both plexiglass and polycarbonate. Bends up to 90 degrees work fine.
Manufacturing cases from sheet materials (or printing) will always cost more than casting.

Answer 3

With such a formulation of the question, I advise you to use a 3D printer (or a store that provides such a service).

Answer 4

There are ready-made "enclosures for equipment made of ABS plastic" (and google it)

Answer 5

If we are talking about bulk purchases, then you should pay attention to Chinese suppliers, they will do anything with a large volume. But as far as delivery is concerned, it's not very convenient here.
The second option is a direct supplier - a plant for the production of polymer products or plastic. As well as small firms that have the appropriate equipment. The same Intercross - they make different ones - but the price bites.
