3D part design with OpenScad #24-Adding text capabilities to the pipe fitting module

I wanted to be able to mark the size of the different branches,so I added the capability to the pipe fitting module:

I added a text input to each of the existing branches,then set up a "text" module:

Just copy and paste the revised code into the editor pane in OpenScad:

(Update 6/4/2022, the text wasn't moving with the branches  when rotate all was used, I fixed it by adding  rotate all for  x,y and z in the text sections and now the text moves properly)

If you want the lettering to be recessed instead of raised just comment out the module call and enable it in the difference section:

If you want to change the direction of the text just change "ltr"(left to right) to "ttb"(top to bottom):
