The New Hotness

One of the flat-topped pegs anchoring the fuzzy black upholstery / carpet to the back of the rear seats went walkabout a while ago, but the situation only became critical after I vacuumed the crud out of the car.

Living in the future simplifies things:

Upholstery Peg - solid model — Upholstery Peg – solid model

Rather than getting all fancy with barbed ends and suchlike, I just slathered the stem with hot-melt glue, jammed it in place, and waited a few breaths:

Upholstery peg - installed — Upholstery peg – installed

The vivid yellow stuff is seat cushion foam.

3D printing is wonderful for simple parts like that.

The OpenSCAD source code is simple enough:

// Upholstery pin for Subaru back seat
// Ed Nisley KE4ZNU
// 2024-09-13

HeadThick = 1.5;
HeadOD = 25.0;

PegLength = 10.0;
PegOD = 8.0;
SlotWidth = 1.5;

rotate_extrude(angle=360,$fn=32)
    polygon(points=[[0,0],[HeadOD/2 - 1,0],[HeadOD/2,HeadThick],[0,HeadThick]]);

difference() {
    rotate(180/8)
        cylinder(d=PegOD,h=10.0,$fn=8);

    translate([0,0,HeadThick ])
        cylinder(d=PegOD/2,h=PegLength,$fn=8);

    for (a=[0,90])
        rotate(a)
            translate([0,0,PegLength/2 + HeadThick + 1.0])
                cube([SlotWidth,10.0,PegLength],center=true);

}
