Generating Random Imperfections

I am looking for ideas on how to model/generate imperfections on objects modeled in OnShape.
I user onshape for modeling items for 3D printing. 

Right now I am revisiting a model of a padlock that I made for a Halloween prop
This is a photo the original that I 3D printed and painted last year



This year I want to make one that looks a lot more beat up and broken
I have already modified the model to break it up into 'broken' pieces




What I am looking for now is ideas on how to distress the surface of the front face and pieces of the shank.
Pitting, scaring, dents, etc.  I could do this with a Dremel tool after printing (which was my original plan)
But I thought it might be better to try modeling these imperfections so that I get these effects in the print itself

Has anyone tried doing something like this in On Shape before?

    I think, by its nature, Onshape isn't really designed for those kinds of 'cosmetic' features. You could certainly do things manually, but that sounds like a lot of work. 

    If you want to do something before printing, I would look at something like Meshmixer after exporting the STL from onshape: http://www.meshmixer.com/

    Bump maps can turn applied visual textures into 3D texture in an mesh model. Not in Onshape though. I don't think in Meshmixer either. Things like Rhino (not ideal for this) or Zbrush or any 3D animation package like 3DSMax or god forbid Houdini (massive learning curve).

    I think the Dremel would be easiest :smile:

    You could try the Sculpt Face FeatureScript: https://cad.onshape.com/documents/b8730d44070bc0466ad80444/v/f33e89a2df8c548621ea2b0f/e/ec46353fdee854c09f4deddb

    You might be able to define local areas with sketches, then use the Scupt tools to deform the surfaces.

    This recently released YT video by Prusa illustrates some interesting tools that seem appropriate for what you want to do and some of them are free.

    Blender could definitely work for what you want and is free, but it’s got a unique UI that can make it tough for beginners (source: am a beginner). Beyond that, Dremel is a pretty good option for your project.

    The simplest option I've used: download an image from a texture, import it to 3d Builder (microsoft and free), export to stl, import the stl in onshape.
