This is a rugged waterproof box with hinges and latches based on https://www.thingiverse.com/thing:3338826 by zx82net. This box uses the same excellent latch and hinge mechanism, but the box and lid have been redesigned for a more rugged look. The provided Fusion360 file also uses separate parameters for the box and the lid.The box can be made waterproof by printing a seal in flexible filament, such as TPU, or by cutting a large 2mm thick o-ring to the appropriate length. (There is also a version without the seal ring.) An alternative method is to fill the seal notch with DIY silicon sealant, wipe away any excess, and let dry several hours.The latches and hinges are held in place with 20mm M3 screws. You need 8 screws in total. The hinges are springy, so they apply static pressure to the seal when the box is closed. There are two types of latch, one is a simple clip, the other is a two part mechanism which acts as a cam, which can apply significant static pressure to the seal. You can swap out the latches after assembly, so you can try both and choose which you prefer.Here is a video of the latch operation:https://youtu.be/6OlaYMMWIgAYou can adjust how tight the mechanism is by scaling the x&y size of the latches or hinges in your slicer, (a change of 2% is enough to make a significant difference).CustomizationYou cannot scale the box directly in your slicer, or the screw holes will no longer be correct. I have included the fusion 360 f3d archive files.These are parameterized, so you can adjust the size by changing the length, width, corner radius and height parameters (Design menu > Change Parameters). I recommend to not go below Height=16 mm for the box and the lid and a minimum size of Length=80 x Width=40 mm, Radius=4. Feel free to experiment with other dimensions.NOTE: v2.0 fixes most of the problems with the Fusion 360 model breaking when being resized. The trick is to resize in small steps: don't resize the width or length from 80 to 160, but resize to 100, then 120, then 140, and then 160. I have also included a .stp file for folks who don't use Fusion 360.Enjoy, and please share any customizations you make.
