Using OpenScad I ended up with this .. a nice minimal design
Openscad file (Jup thats all)
difference(){ difference(){ union(){ cube([96,30,12],center = true); translate([41,0,5]) cube([15,30,23],center = true); translate([-41,0,5]) cube([15,30,23],center = true); } cube([90,30-6,24],center = true); } union(){ difference(){ translate([0,0,5]) cube([90,20,30],center = true); translate([0,0,5]) cube([77,20,35],center = true); } } }
