Petrus paper punching machine guide

thingiverse

I've been tinkering with an old paper punching machine for years, but there's one crucial part missing - a plastic piece that keeps the paper in line. The holes need to be precisely placed, and without this piece, it's impossible to get them just right. So, I decided to take matters into my own hands and create one from scratch. I figured the simplest way to make this small but vital component would be to use a 3D modeling software like OpenSCAD. Its cube, cylinder, and sphere functions are perfect for creating geometric shapes like this plastic piece. I've included the OpenSCAD code below - it's not exactly elegant, but it gets the job done. // define dimensions piece_width = 30; piece_height = 10; hole_diameter = 5; // create a cube to serve as the base of the piece cube([piece_width, piece_width, piece_height]); // add a cylinder for the hole cylinder(h=piece_height, r=hole_diameter/2); I'm not one for elaborate designs or fancy coding, so I've kept it simple. This should do the trick!
