Faucet wheel, FreeCAD, parametric

*Creating STL files with FreeCAD 0.17 seems problematic, at least with this freecad file. It picks and includes one subpart that is NOT meant to be included.*

Parameters:
Combo View > Body_Main > Pad > Sketch: Property tab
- the named constraints that has no formula can be manipulated to achieve different looks of the wheel.

Note though that some combinations makes the sketch break up;
the only easy and functionally SAFE remedy is to reopen the file, do not save ;-).

The last two UNNAMED constraints shows the INNER (spokes) and OUTER diameters of the wheel.

Some combinations requires adjustment of Fillets, e.g. see the *_50.fcstd file. The *_03.fcstd has a simlar adjustment that is makes that setup work, but where "divs" can be adjusted up. Also: Don't jump from divs 50 to 3 and expect that to work; do it in a number of steps. *This seems to me be one limitation of the freecad solver*
