3D Printing Clearence Test

A printer agnostic, parametric, inspectable and usable clearance test for 3D printing

Requirements

Written in OpenSCAD. Requires the following libraries:

• https://github.com/JustinSDK/dotSCAD;
• https://github.com/thehans/funcutils.

Usage

You can pass to the main module a list of clearances.

clearences = [0.1, 0.2, 0.3];
main(clearences);

As alternative you can use the calculate_clearences function. It accepts 4 parameters:

1. line_height: the line height at which you will slice the model;
2. tests_number: how many test you want to create;
3. step: how much each test should grow;
4. difference: how much you want to go down from line_height for the first test.

clearences = calculate_clearences(.1, 5, .05, .05);
main(clearences);
