+TITLE:
+Stable and waterproof OpenSCAD case by pbtec
+
+DESCRIPTION:
+
+highly scalable case for 3D printing. Try it out!
+
+Optimized for Openscad Customizer. Activate it under view/customizer and play around ;-)
+
+No Support needed to print
+
+- 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 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.
+

+TITLE:
+Stable and waterproof OpenSCAD case by pbtec
+
+DESCRIPTION:
+
+highly scalable case for 3D printing. Try it out!
+
+Optimized for Openscad Customizer. Activate it under view/customizer and play around ;-)
+
+No Support needed to print
+
+- 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 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.
+

+TITLE:
+Stable and waterproof OpenSCAD case by pbtec
+
+DESCRIPTION:
+
+highly scalable case for 3D printing. Try it out!
+
+Optimized for Openscad Customizer. Activate it under view/customizer and play around ;-)
+
+No Support needed to print
+
+- 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 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.
+
+for waterproofness see https://blog.prusaprinters.org/watertight-3d-printing-part-2_53638/

+TITLE:
+Stable and waterproof OpenSCAD case by pbtec
+
+DESCRIPTION:
+
+highly scalable case for 3D printing. Try it out!
+
+Optimized for Openscad Customizer. Activate it under view/customizer and play around ;-)
+
+No Support needed to print
+
+- 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 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.
+

+TITLE:
+Stable and waterproof OpenSCAD case by pbtec
+
+DESCRIPTION:
+
+highly scalable case for 3D printing. Try it out!
+
+Optimized for Openscad Customizer. Activate it under view/customizer and play around ;-)
+
+No Support needed to print
+
+- 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 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.
+

+
+This directory is intended for project header files.
+
+A header file is a file containing C declarations and macro definitions
+to be shared between several project source files. You request the use of a
+header file in your project source file (C, C++, etc) located in `src` folder
+by including it, with the C preprocessing directive `#include'.
+
+```src/main.c
+
+#include "header.h"
+
+int main (void)
+{
+ ...
+}
+```
+
+Including a header file produces the same results as copying the header file
+into each source file that needs it. Such copying would be time-consuming
+and error-prone. With a header file, the related declarations appear
+in only one place. If they need to be changed, they can be changed in one
+place, and programs that include the header file will automatically use the
+new version when next recompiled. The header file eliminates the labor of
+finding and changing all the copies as well as the risk that a failure to
+find one copy will result in inconsistencies within a program.
+
+In C, the usual convention is to give header files names that end with `.h'.
+It is most portable to use only letters, digits, dashes, and underscores in
+header file names, and at most one dot.
+
+Read more about using header files in official GCC documentation:
+
+* Include Syntax
+* Include Operation
+* Once-Only Headers
+* Computed Includes

+This directory is intended for PlatformIO Test Runner and project tests.
+
+Unit Testing is a software testing method by which individual units of
+source code, sets of one or more MCU program modules together with associated
+control data, usage procedures, and operating procedures, are tested to
+determine whether they are fit for use. Unit testing finds problems early
+in the development cycle.
