Using Openscad and the Thingiverse customizer feature, I was able to create this resource to easily create 3d models of hole patterned tubes. Essentially, Thingiverse allows users to make calculators that generate 3d models based on user input of specific variables, rather than make the entire model over and over again. This feature can be very useful because it allows many similar files to be made at once, rather than individually modeling a bunch of parts that have minuscule differences.
The 3d model generator that I created can be found here:
http://www.thingiverse.com/thing:1649104
Once you open that link, hit customize and you can make your own hole patterned tubes quite easily (even without knowledge of 3d modeling).
Has anyone else made 3d model generators like this one? Does anyone have any ideas for other generators I/someone else should make in the future?
Keep in mind when testing that this is just my first version, and I plan on adding more functionality/fixing bugs in the future. If you have any questions, comments, notice any bugs, or have any recommendations for more features please let me know.
There's nothing wrong with taking suggestions but be sure not to let other people tell you how your team should be run. - NickE [more]
