ShelfBracketSpacer.foocad

I have lots of shelving brackets, for 3 shelves, and rather than trying to align the brackets perfectly on the wall, I add spacers of the required thickness to each bracket.

For thick spacers, use high perimeters, but low infill, as only the edge needs to take weight (the bracket has a void in the middle).

class ShelfBracketSpacer : Model {
    
    @Custom( about="The space between the shelf and the bracket" )
    var space = 4.0//1.0

    @Custom( about="margin and height of the inner part" )
    var inset = Vector2( 2.0, 1.2 )

    fun profile() = Square( 252, 27 ).roundAllCorners(2).centerY()

    override fun build() : Shape3d {
        val profile : Shape2d = profile()


        val hole = Circle( 4 )
        val holes = hole.translateX( 22 ) + hole.translateX( 150 ) + hole.translateX( 215 )

        val gaps = Square( (profile.size.x - 40) / 4 - 10, profile.size.y- inset.x * 2 - 2 * 2 ).center()
            .tileX( 4, 10 ).rightTo(profile.right - 20)

        val base = profile - gaps - holes

        val inner =  profile.offset( - inset.x )
        val innerRing = inner - inner.offset( -2 )


        return (base).extrude( space ) +
            innerRing.translateX( inset.x ).extrude( space + inset.y ).color("Orange")

    }
