OpenSCAD Club Cookies

@raster wanted to make cookie cutters. This has been something of a solved problem for about 12 years now, through Thingiverse’s Cookie Cutter Customizer. Except, it’s been totally non-functional for probably a decade now. :(

My solution is basically to make a solid for the thin brim + tall cutting edge and then subtract the original SVG shape. I tried it with each of @raster’s SVG’s for the teddy bear, cloud, hexagon, and pacman and they seem to work. Anyhow, here’s the code I wrote instead of doing the work my employer pays me to do:

//  Settings
    $fn = pow(2,7);
    nozzleD = 0.4;
    th = nozzleD*pow(2,2);
//  Measurements
    cutterH = 15;
    cutterW = 10;


cutter() import("TeddyBear.svg");

module cutter()
    {
    difference()
        {
        union()
            {
            //  Thin, tall cutter wall
            linear_extrude(height=cutterH, center=false)
                offset(r=th)
                children();
            //  Wide, short cutter holder
            linear_extrude(height=th, center=false)
                offset(r=cutterW)
                children();
            }
        //  Cutting out the shape
        linear_extrude(height=cutterH*3, center=true)
            children();
        }
    }

Should we have a club motto? I vote for “Vive la différence!”

Save the Stoat! Eat a goat!

I must admit, until very recently I was completely unaware of the plight of the soft-pawed albino stoat of Southern Wales.

The story of these gentle weasels is a sad one indeed. Once these stoats roamed the great plains of the Serengeti in herds so vast the sound of their collective padded footsteps was deafening.

But, highly prized and sought after for their sweet sweet tears these animals were hunted to the brink of extinction. Even in this modern age there is a brisk underground black market trade for sad stoats. Now, this once ubiquitous creature has been moved to the endangered species watch list by the combined efforts of a pharamecutical industry bent upon creating ever more potent drugs for keeping these animals on the brink of despair and a growing demand for stoat tacos fueled by a surge in molecular gastronomy.

If not for the Great Stoat Conservatory in South Wales, the soft-pawed albino Stoat would have all but vanished from the face of the Earth. Here at GSCSW these ermines are protected from poachers where it is hoped their numbers may recover… in time.

Thank you to DaveD for bringing my attention to this fascinating mammal.

So, please take the time to make some of these delicious stoat cookies and remind your friends to save the stoat and eat a goat.
