View source for From 3D printer model to CNC machining


== Disclaimer ==
Lets assume we have modelled a 3D printable part and it has been test printed and it works.
Just because it's from plastic it's too weak for some application or it's not heat resistant enough.
What if we wanted to take a 3D design and order aluminum or steel parts to be machined in factory?

There is a lot that has to be specified for well designed mechanical part, various tolerances, roughness of surfaces.
This information will be missing when we hand over just some exported 3D model, so they have to be additionaly supplied.

I succeeded to get quick quote with properly rendered part by uploading .step file.

==== Workflow: OpenSCAD to Weerg service using FreeCAD ====
1.take your .scad design

2.run FreeCAD

3.choose OpenSCAD workspace

4.open document -> .scad

5.now you should see your finished part

6.select only the finished part from list of object on panel on the left

7.export -> .step

8.upload to weerg.com  get instant quote and choose CNC machining


If you want to add threaded holes you can add them manually in their instant quoter, but you will have to have holes of precise
diameter in your .scad design. If you have precise hole dimensions they will appear in a list in quoter.
2.5 mm hole is for M3 threaded hole, 3.3 mm is for M4 and 4.2 mm is for M5.
