Hi, i just complete my first print on my prusa i3 using repetier-host. It's a test part (.stl) i download from thinkiverse i think. How do i find the mesure the part shoud be ?
I'm a machinist so i know how to use a caliper but i want to analyse the .stl file. I attach the files.

Thanks

Import the file into something like freecad and use the measuring function.
Under the part workbench.
Youl need to turn it into a solid and then probably simplify the the part.
Then you can use the measure function and select 2 points, edges or faces to measure.

Freecad is open source.

thanks for your help !
