corner protectors in OpenSCAD (6)

Don't just jump in here, start from Part 1! Now it's time for the big finish. For our final decorative flourish, we're going to put a large rounded corner on each of the three surfaces with screw holes in them, with the radius of the corner determined by how close the screw hole is to the edge. To do this we'll need to learn a little about rotate_extrude however, one of the niftier if also more confusing OpenSCAD functions I've had the pleasure of using. And by the way, if you know a little something Read more [...]

Don't just jump in here, start from Part 1! So we've basically got fillet edges on our piece now, but you'll notice that the actual corners are sharp and not so great looking. To make the corners look consistent with the edges, we'll need to subtract the exterior of one quarter of a sphere from the corner in the same way we subtracted the exterior of one quarter of a cylinder to get the fillet edge. The code to do such a thing looks like this: difference () { translate([-pad, -pad, -pad]) Read more [...]

Don't just jump in here, start from Part 1! So far we've got a single object in place with two tweakable variables and a little bit of basic OpenSCAD code under our belt. It's time now to learn some new commands and a very handy new concept: the module. We'll use rotate, union and a module call to add screw holes with head recesses to our drawing. The first thing we'll want to do is define a few new variables related to our screw dimensions and placement. Not knowing what kind of screws Read more [...]

Don't just jump in here, start from Part 1! By the way, if you're already convinced and serious about learning OpenSCAD, just Google "OpenSCAD tutorial" and you'll find some great options out there. This is as much an exercise for me in "learning by teaching" as anything else. That said, anyone still left in the room can join me in making a "corner protector" (I seem to sometimes call it a "corner support" without rhyme or reason). So to start making our corner protector, open OpenSCAD Read more [...]
