Stable and waterproof OpenSCAD case V7.3 by pbtec

Highly scalable electronic case for 3D printing. Try it out!
Optimized for Openscad Customizer. Activate it under view/customizer and play around ;-)
Openscad is free opensource software. You can download it here: https://openscad.org/

Fixed version 7.3
It seems that special characters in the code have again led to the code not working properly for some. I apologize for this. I have now created a new version 7.3 where this is fixed. I would be very interested to know if everything works as expected for you now. Thanks for your feedback in the comments

Enhancements in Version 7.2:

  • Hot melt copper nut support
  • Screw hole options: Can be configured to pass through the entire case, with the option to position the nut at the bottom of the case
  • Flexible mounting options: 1 to 3 holes on all sides for cable glands or switches
  • Improved PCB support: Now compatible with up to 3 different PCBs holders instead of just one
  • Base bottom mounting holes added (not recommended if the housing should be highly waterproof)
  • Gasket can now be printed (TPU).
  • Expanded screw support: In addition to countersunk screws, round, flat, and hex head screws are now supported

I would love to hear whether you like the new version!

No support needed to print

You don't know Openscad? No problem. Export the stl file from Openscad (F6 then F7). Then Import the stl file into your best known 3d program to make holes for example.
You can also make the holes afterwards with the drilling machine.

Additional Screws (M2,M2.5,M3,M4 or M5), the matching nuts (hex or square) needed.
If you want to protect your electronics from humidity also “silicone sealing cord” is needed. Available at AliExpress or ebay.

For waterproof cases you can use silicone sealing cord with diameters from 1 to 3mm
To use also without sealing cord. The groove and ridge gives the housing a high stability and tightness.
Use of regular nuts or square nuts
Define outer vertical radius of corners
Echo output in console shows inner and outer size and more
Echo output shows the needed length of the screws
Use screws from m2 up to m5
Default are 4 screws at each corner. For large cases add addtional ones in the middle of both x and y sides if needed
Use several predefined wall mount holder, some with multiple mounting holes (up to 3)

Important!
If you use standard or square nuts, you need to pause the printer a certain level to insert the nuts
If you need a stable and waterproof case please print with 100% infill
I'm aware that sometimes, when using too big or too small parameters, there are some rendering issues. To prevent such issues change only one parameter at once and check the result.

I never tested the water proofness of this case. For more information see https://blog.prusaprinters.org/watertight-3d-printing-part-2_53638/
