Creating a 3D printed waterproof box sounds simple enough. But there are many factors to consider and it is not as easy as it first seems.
|Silicone aquarium tubing works perfectly but only when perfectly placed in the groove and the cut ends are perfectly connected. 12 hour tests have kept out all water, while subsequent tests of just an hour or so would see water make it in.|
3D printing settings like shell thickness and infill are important. So is designing a seal. There is no readily available design guides on how to do this. It really is just a matter of trying to reverse-engineer examples of reliably waterproof boxes already onhand.
Then there is testing. Testing to see if something that took hours to print out at 100% infill always begins with a sense of impending doom.
