<p>Does anyone know of a method, app, technique to &quot;dumb down&quot;, if you will, larger models to do a quick initial print to check that it fits the real world proof of concept that it was designed for.</p>

# Convert model to "skeleton / prototype" model for quick real world "Proof of Concept"

Does anyone know of a method, app, technique to "dumb down", if you will, larger models to do a quick initial print to check that it fits the real world proof of concept that it was designed for.

I am not talking about 0.3 mm draft printing, I already do that... But is there a way or method, to kind of "skeleton" the large print, print it in let's say, 25 % of the actual time to test its physical application. Scaling down works, in some situations, but I would prefer a 100 % model, just "simplified / skeleton'ized", still with the correct dimensions.

You can modify files yourself or use an [online application](https://www.voronator.com/) to do that for you.

However, you may create skeleton like models, but it is not always faster to print these models; they may have less material, but retraction may cause the printing time to be actually longer than printing the original at low density infill.
