Kinect/3D Scanner Calibration Pattern

thingiverse

This OpenSCAD script will generate a grid pattern of small cuboids attached to a large flat cuboid. The heights of the smaller cuboids will alternate sequentially. The user can specify the number of rows & columns as well as the length & breadth of the smaller cuboids and the separation between adjacent cuboids. The Number of different heights and the difference in height between smaller cuboids can be specified too. The user can also choose whether or not to add Keyed connectors so that they can print multiple items that can then be easily connected together to for an arbitrarily large grid The overall effect will be like the tread pattern of a mountain bike tyre or a 3D checker board. Instructions Warning: DO NOT PRINT THIS WITHOUT SUPPORT MATERIAL ENABLED! At the moment it uses far too much support material, and I am unsure if this will work well without support. Wait until it gets to version 1.0 if you are concerned with this. Version_number < 1.0 generally not ready to be used by others Version_number ==1.0 ready to be used provided you know what you're doing Version_number > 1.0 safe for general use To Do: add ability to split up a large grid into multiple pieces to fit a users specific 3D printer bed add ability to separate print into click together smaller cuboid inserts and large cuboid grid clean up code! Changes: 0.6 add support for symmetric keyed joint at edges courtesy of Relet's derivative http://www.thingiverse.com/thing:6214 of WilliamAAdams http://www.thingiverse.com/thing:5867 fixed small error with if/else if/else statement for calculating if ibject would fit within print envelope 0.5 add ability to have user definable arbitrary number of small cuboid heights 0.4 Add ability to check if item is small enough to fit into user's print envelope Warn user when item is too big and prevent from generating a 3D object Warn user when item is near max envelope but still generate 3D object Hollow out shape to reduce print time and cost 0.3 Added ability to generate small cuboids with 3 different heights 0.2 Added ability to generate pattern with 2 different heights 0.1 First version with ability to generate basic grid with small cuboids all same height
