Glueless and screwless waterproof plastic enclosure

Glueless and screwless waterproof plastic enclosure

Hey guys,

I want to design my own plastic enclosure that is waterproof (maybe 3D print it). In basic terms, it would be a rectangular basin type design with a lid that fits over the top. Once it fits over the top. It should not be able to be removed.

I want to avoid using glue or screws. What are my other options?
I was thinking that a snap fit design might work but it may not be possible to make it waterproof.

RE: Glueless and screwless waterproof plastic enclosure

How waterproof? Everything leaks if you have a sensitive enough measuring system. For very low pressure differential you may be able to get a snap fit to give a "waterproof" seal. Zip lock bags do it all the time. If your requirements are more severe you will probably need some kind of elastomeric seal.


The Help for this program was created in Windows Help format, which depends on a feature that isn't included in this version of Windows.

Snap fit plus an elastomeric seal, perhaps something like this:

RE: Glueless and screwless waterproof plastic enclosure

I wouldn't recommend trying to 3D print a waterproof enclosure as most 3D printable materials are porous and readily allow water through. Ultrasonic welding can produce a hermetic seal or snaps with a gasket like dgallup and CoryPad said would work.

Research Report - Mass Customization Placing Design in the Customers Hands
Products come in all shapes and sizes, and customers demand solutions tailored to their needs. With mass customization software, these two facts can be reconciled in an automated, customer-facing experience called a product configurator. In this engineering.com research report, we examine the different levels of mass customization with the pyramid of product configurators. Taking a look at real-world case studies, we discover how the highest level of the pyramid can enable true engineering automation, saving time and increasing customer satisfaction. Download Now
Research Report - Test and Simulation Survey
We at engineering.com continually hear how engineers and designers will be doing simulation, such as FEA and CFD, and that they will be doing it early in the design cycle. Is this wishful thinking? We found out what it is really like in industry. Read more now. Download Now
