1+Plunger
2+
3+Disclaimer:
4+ All units are based in SI units system (metres, kilograms, seconds and radians). This should be the standard in FreeCAD IMO.
5+ π(pi) is equal to 3.141592653589793 (Double precision)
6+
7+Firstly go to Edit->Preferences->General
8+
9+Then,
10+
11+ Switch unit system to MKS (m/kg/s/degree), because this is the closest to SI unit system.
12+ Number of decimal to at least 3, I personally have 6.
13+ Ignore factional inch.
14+
15+Click "Apply" then "Ok".
16+
17+From the start page, click "Create new..."
18+Switch to part workbench
19+
20+Cup
21+ 1. Click "Creation of parametrized geometeric primitives"
22+ Switch from "Plane" to "Sphere"
23+ Radius of 0.075 m
24+ U parameter of pi * 1rad (click the round f(x) to enter the formula)
25+ V parameter of -pi / 2 * 1rad and pi / 2 * 1rad
26+
27+ 2. Click "Creation of parametrized geometeric primitives"
28+ Switch from "Plane" to "Sphere"
29+ Radius of 0.065 m
30+ U parameter of pi * 1rad
31+ V parameter of -pi / 2 * 1rad and pi / 2 * 1rad
32+
33+ 3. Make a cut by selecting the larger half sphere (Sphere) first then the other half sphere (Sphere001)
34+
35+ 4. Create a tube with
36+ Outer radius of 0.015
37+ Inner radius of 0.01
38+ Height of 0.04
39+ Z = 0.07
40+
41+ 5. make union with the above cut and tube
42+
43+ 6. Fillet the selected edge with the edge between the tube and the cut (Edge5) with
44+ radius of 0.02m
45+
46+Handle
47+ 1. Create a cylinder with
48+ Radius of 0.015
49+ Z at 0.07
