TLDR;

A bathroom catch box to collect used razor blades.

openSCAD

I was just looking for a nice way to hollow objects in openscad and it ended up with this clean box to collect used razor blades.  

This is just a prototyp print using B-ware transparent PLA but went out so good that it is in use since i printed it.

Printed on a  Prusa Core One without support and got a nice transparent look.

openSCAD

include <BOSL2/std.scad>
$fn=90;

module razor_drop(w=1.35){
module cube2(d=0){ // shaped like an old razor blade
cuboid([84,26,100]-[d,d,d],rounding=w2);
cuboid([74,42,100]-[d,d,d],rounding=w2);}

zrot(90)union(){
difference(){
up(40)yrot(-45)
difference(){
cube2();
cube2(w); // hollow
translate([20,0,52])yrot(45) // cut the slit
cuboid([2,30,10], rounding=1, except=[TOP,BOT]);
}
cuboid(100,anchor=TOP);
}
intersection(){ // add the bottom
up(40)yrot(-45)cube2();
cuboid([100,100,w], anchor=BOT);
}
}
}//
razor_drop();
