Introduction
Challenge
The Build Plate library is a utility that will add a representation of a build plate to your file so you can know exactly where your model will be on the plate when you print. It will not be part of the model, but is just a representation. You can specify what kind of plate: the Replicator 1, the Replicator 2, the Thingomatic, or a plate of your own specification.

To use this library:
  1. Download it from by clicking here.

  2. Here are the following parameters that you can set: 
    //for display only, doesn't contribute to final object
build_plate_selector = 0; //[0:Replicator 2,1: Replicator,2:Thingomatic,3:Manual]

//when Build Plate Selector is set to "manual" this controls the build plate x dimension
build_plate_manual_x = 100; //[100:400]

//when Build Plate Selector is set to "manual" this controls the build plate y dimension
build_plate_manual_y = 100; //[100:400]

build_plate(build_plate_selector,build_plate_manual_x,build_plate_manual_y);


  3. Create a folder called utils and save build_plate.scad in that directory.

  4. Create a new OpenSCAD file just above the utils directory.

  5. Place these lines at the top of your new OpenSCAD file should be: 
    use <utils/build_plate.scad>
//set your build plate
build_plate_selector = __; //[0:Replicator 2,1: Replicator,2:Thingomatic,3:Manual]

//if set to "manual" set the  build plate x dimension
build_plate_manual_x = 100; //[100:400]

//if set to "manual" set the  build plate y dimension
build_plate_manual_y = 100; //[100:400]

build_plate(build_plate_selector,build_plate_manual_x,build_plate_manual_y);

//create some object
    If you don't create an object, you will encounter an error. Make sure you include an object. You can test the build plate with a simple cube().
