Summary

I designed and printed this to use in the tests for a case to an USB camera module.

How I Designed This

FreeCAD Python script


import FreeCAD as App
import Part

def buracoNoCanto(placa, diametro, distancia):
    d1, d2 = distancia, 38-distancia
    placa = placa.cut(Part.makeCylinder(diametro/2, 2).translate(App.Vector(d1, d1, 0)))
    placa = placa.cut(Part.makeCylinder(diametro/2, 2).translate(App.Vector(d1, d2, 0)))
    placa = placa.cut(Part.makeCylinder(diametro/2, 2).translate(App.Vector(d2, d1, 0)))
    placa = placa.cut(Part.makeCylinder(diametro/2, 2).translate(App.Vector(d2, d2, 0)))
    return placa

# new doc
doc = App.newDocument()

# create board
placa = Part.makeBox(38, 38, 2)

# corner holes
placa = buracoNoCanto(placa, 2.5, 2)
placa = buracoNoCanto(placa, 2.6, 5)
placa = buracoNoCanto(placa, 2.4, 7)

# cuts
placa = placa.cut( Part.makeBox(5,1,2).translate(App.Vector(2, 2, 0)))
placa = placa.cut( Part.makeBox(1,5,2).translate(App.Vector(2, 2, 0)))
placa = placa.cut( Part.makeBox(5,1,2).translate(App.Vector(2, 35, 0)))
placa = placa.cut( Part.makeBox(1,5,2).translate(App.Vector(2, 31, 0)))

# cuts
placa = placa.cut( Part.makeBox(5,1,2).translate(App.Vector(31, 2, 0)))
placa = placa.cut( Part.makeBox(1,5,2).translate(App.Vector(35, 2, 0)))
placa = placa.cut( Part.makeBox(5,1,2).translate(App.Vector(31,35, 0)))
placa = placa.cut( Part.makeBox(1,5,2).translate(App.Vector(35,31, 0)))

# cuts
placa = placa.cut( Part.makeBox(1,20,2).translate(App.Vector(2,9, 0)))
placa = placa.cut( Part.makeBox(1,20,2).translate(App.Vector(38-2-1,9, 0)))
placa = placa.cut( Part.makeBox(20,1,2).translate(App.Vector(9,2, 0)))
placa = placa.cut( Part.makeBox(20,1,2).translate(App.Vector(9,38-2-1, 0)))

# cuts
placa = placa.cut( Part.makeBox(1,22,2).translate(App.Vector(4,8, 0)))
placa = placa.cut( Part.makeBox(1,22,2).translate(App.Vector(38-4-1,8, 0)))
placa = placa.cut( Part.makeBox(22,1,2).translate(App.Vector(8,4, 0)))
placa = placa.cut( Part.makeBox(22,1,2).translate(App.Vector(8,38-4-1, 0)))

# lens
placa = placa.fuse( Part.makeBox(14,14,2).translate((12,12,2)) )
placa = placa.fuse( Part.makeCylinder(7,12).translate((19,19,0)) )
placa = placa.cut( Part.makeCylinder(5,12).translate((19,19,0)) )

doc.addObject("Part::Feature", "Placa com Buracos").Shape = placa
