There may be a simpler method.

It is this model.
Mobius_Strip-2round&holes

  1. Step 1:

    Step1
    Please turn ON the next option.

    Parameters and Measure-Knowledge-Parameter Tree View-'With value':ON
    Infrastructure-Part Infrastructure-Display-'Parameters':ON

  2. Step 2:

    Step2
    Create two parameters of type Real.

    'Twist_Count' : 1
    'Hole_Count' : 13

  3. Step 3:

    Step3
    Create Sketch, and, please make a semicircle.
    The semicircular radius, please use 'Edit Formula'

    -Formula Editor-
    Hole_Count *2.5mm

  4. Step 4:

    Step4
    Create Line.

    Point:Sketch.1\Vertex
    Direction:yz plane
    Start:-20mm
    End:20mm

  5. Step 5:

    Step5
    Create Axis System.

  6. Step 6:

    Step6
    Rotate to 'Sketch.1'.

    Element:Sketch.1
    Axis:Axis System.1\Z Axis
    Angle:180deg

  7. Step 7:

    Step7
    Create Sweep Surface.

    -Swept Surface Definition-
    Profile:Line.1
    Guide curve:Sketch.1
    Surface:xy plane
    Angle: 'Law' click

    -Law Definition-
    Law type:Liner
    Start value:0deg
    End value: right-click. select 'Edit formula'

    -Formula Editor-
    (180deg*0.25)*Twist_Count

  8. Step 8:

    Step8
    Please perform copy & paste of three times of 'Sweep.1'.
    Please revise the following.

    -Sweep.2-
    Guide curve:Rotate.1
    Start value(Law-Formula Editor):(180deg*0.25)*Twist_Count
    End value(Law-Formula Editor):(180deg*0.5)*Twist_Count

    -Sweep.3-
    Start value(Law-Formula Editor):(180deg*0.5)*Twist_Count
    End value(Law-Formula Editor):(180deg*0.75)*Twist_Count

    -Sweep.4-
    Guide curve:Rotate.1
    Start value(Law-Formula Editor):(180deg*0.75)*Twist_Count
    End value(Law-Formula Editor):(180deg*1)*Twist_Count

  9. Step 9:

    Step9
    Create Sphere.

    Center:sketch.1\vertex.2
    Sphere axis:Axis System.1
    Sphere radius:15mm

  10. Step 10:

    Step10
    Create Circular Pattern.

    Parameters:Complete crown
    Instance(s)(Formula Editor):int(180deg/`Geometrical Set.1\CircPattern.1\AngularSpacing` )+4
    Angular spacing(Formula Editor):720deg/(Hole_Count)
    Reference element:xy plane
    Object:Sphere.1

  11. Step 11:

    Step11
    Create Join.

    Elements To Join:Sphere.1 CircPattern.1
    Check connexity:Off

  12. Step 12:

    Step12
    Rotate to 'Join.1'

    Element:Join.1
    Axis:Axis System.1\Z Axis
    Angle(Formula Editor):`Geometrical Set.1\CircPattern.1\AngularSpacing` *-1

  13. Step 13:

    Step13
    Please perform copy & paste of three times of 'Rotate.2'.
    Please revise the following.

    -Rotate.3-
    Element:Rotate.2
    Angle(Formula Editor):`Geometrical Set.1\CircPattern.1\AngularSpacing`*(int( Hole_Count /4)*1+1)

    -Rotate.4-
    Element:Rotate.2
    Angle(Formula Editor):`Geometrical Set.1\CircPattern.1\AngularSpacing`*(int( Hole_Count /4)*2+1)

    -Rotate.5-
    Element:Rotate.2
    Angle(Formula Editor):`Geometrical Set.1\CircPattern.1\AngularSpacing`*(int( Hole_Count /4)*3+1)

  14. Step 14:

    Step14
    Create Split

    -Split.1-
    Element to cut:Sweep.1
    Cutting elements:Rotate.2

    -Split.2-
    Element to cut:Sweep.2
    Cutting elements:Rotate.3

    -Split.3-
    Element to cut:Sweep.3
    Cutting elements:Rotate.4

    -Split.4-
    Element to cut:Sweep.4
    Cutting elements:Rotate.5

  15. Step 15:

    Step15
    Create ThickSurface(PartDesignWB)
