Why don't you just go to http://www.thingiverse.com <http://www.thingiverse.com> and do a search on "pcb box". I got dozens of hits, many with Openscad source code included. Eg. http://www.thingiverse.com/thing:13979/#files <http://www.thingiverse.com/thing:13979/#files> . They may or may not be exactly what you want but they offer great examples and can be used as starting points for making other Things. -- View this message in context: http://forum.openscad.org/Beginner-needs-help-with-project-tp12117p12130.html Sent from the OpenSCAD mailing list archive at Nabble.com.

Hi again I removed the offending lines at the end of each module and the error went away but I still have 2 problems , The inner box should cut out the center of the outer one but it doesnt , I can understand if it cut out but not centrally because the corner of both cubes have the same origin , the inner cube needs moving in the X,Y and Z by the size of the boxes thickness , but its not cutting out at all and I dont know why and in answer to Michelle as to why not just go to thingiverse and download a box? Well then I wouldnt learn anything and that was the main object of the excercise . If all I wanted was a box I can make one in a couple of minutes in solid works but I was trying to learn to use Scad Don -- View this message in context: http://forum.openscad.org/Beginner-needs-help-with-project-tp12117p12131.html Sent from the OpenSCAD mailing list archive at Nabble.com.

I wasn't suggesting you simply download and print an existing box. I have found that a great way to learn Openscad (or any programming language) is to look at working examples of other peoples' code. I've learned lots from reading Openscad code posted on Thingiverse. You said you were a beginner so it wasn't clear if you knew about this resource or not. That's all. -- View this message in context: http://forum.openscad.org/Beginner-needs-help-with-project-tp12117p12132.html Sent from the OpenSCAD mailing list archive at Nabble.com.

Hi I found the answer to my own question , I had missed off the { and } from the difference function in the last module all I need to do now is center the two boxes relative to each other and I should be getting closer -- View this message in context: http://forum.openscad.org/Beginner-needs-help-with-project-tp12117p12133.html Sent from the OpenSCAD mailing list archive at Nabble.com.

Hi Michelle , I didnt mean to sound ungrateful , its just that pretty much most things I saw on thingiverse had only got an stl file and no Scad file but I can see now that if the Scad file is available then looking at it should be very helpful Don -- View this message in context: http://forum.openscad.org/Beginner-needs-help-with-project-tp12117p12134.html Sent from the OpenSCAD mailing list archive at Nabble.com.

For mine, I set the screw holes to the diameter used to drill for a tap. The 6-32 screws self-tap into that very nicely. The holes in the top of the box then are the size to pass the screw. I found a table online somewhere. Lowering the number of sides in a hole can give nice hexagonal surfaces for tapping into. The one thing I didn't do (yet) on my test box that I would like, is to have the bottom half nest into the top half. But so far it has been ok to just have the two walls meet without any indexing.

An example I have on thingiverse that is a nesting edge box for a pcb is http://www.thingiverse.com/thing:150101, here's the scad file link: http://www.thingiverse.com/download:291446 The scad code is set up with lots of params to resize. It's very basic scad and an easy intro to boxen. I'd be happy to help with any questions about it. --tim On Sun, Mar 22, 2015 at 11:51 AM, david vanhorn <kc6ete@gmail.com> wrote: > For mine, I set the screw holes to the diameter used to drill for a tap. > The 6-32 screws self-tap into that very nicely.

I am a relative beginner too, here is a first stab at something you can start from: module boss() { h = 6; r = 3; $fn = 20; difference() { cylinder(h=6, r=3, center=true); cylinder(h=7, r=2.5, center=true); } } module pcbbox(l=30, w=25, h=1) { co = 12; union() { difference() { cube([l+3, w+3, h+14], center=true); translate([0, 0, 3]) cube([l, w, h+15], center=true); } translate([(l-co)/2, (w-co)/2, 0]) boss(); translate([-(l-co)/2, (w-co)/2, 0]) boss(); translate([(l-co)/2, -(w-co)/2, 0]) boss(); translate([-(l-co)/2, -(w-co)/2, 0]) boss(); } } pcbbox(50, 40, 1); On Sun, Mar 22, 2015 at 9:59 AM, Tim Deagan <tim@deagan.net> wrote: > An example I have on thingiverse that is a nesting edge box for a pcb is > http://www.thingiverse.com/thing:150101, here's the scad file link: > http://www.thingiverse.com/download:291446 > > The scad code is set up with lots of params to resize.
