This is a tool (inspired by http://www.thingiverse.com/thing:26025) to help you bend hookup wires of the correct length for your electronics breadboard projects. You can find a lot more detail at http://thegaragelab.com/posts/breadboard-wire-bender-tool.html


The simplest way:

Download the STL file, run it through your slicer and print. The STL provided goes from 'skip 2 holes' to 'skip 12 holes' and will print with a bed area of
15cm x 15cm (6 inch x 6 inch).

Getting Funky:

Download the OpenSCAD source file, adjust the parameters at the top of the file, generate the STL, run it through your slicer and print. The parameters are fairly self explanatory (for more details go to http://thegaragelab.com/posts/breadboard-wire-bender-tool.html).

I was getting some weird 'artifacts' upon compiling, so I changed both of the subtracted cube's HEIGHT to HEIGHT+1 in the 'difference' statement

 difference() {

  cube(size = [ plate_length, plate_width, HEIGHT ], center = true);

  translate(v = [ 0, plate_xlat, 0 ]) {

    rotate(a = [ 0, 0, angle ]) {

      cube(size = [ plate_length * 2, plate_width, HEIGHT+1 ], center = true);



  translate(v = [ 0, -plate_xlat, 0 ]) {

    rotate(a = [ 0, 0, -angle ]) {

      cube(size = [ plate_length * 2, plate_width, HEIGHT+1 ], center = true);





Thanks for pointing that out,  I've found similar problems with some other OpenSCAD things I've been working on - although the temptation is to make everything exactly the right size objects being subtracted need to be slightly larger than 'exact' so as not too leave thin 'invisible' layers that can confuse the Slicer.

I'll update the OpenSCAD file in the near future.
