Sprue a helper for small parts

See install section for additional notes.

Sprue 1 & 2 are nearly identical. 2 uses the new formula, so it is rotated correctly. 3 bypasses the problem I was having with Makerware. 4 is set so that if you scale down by a factor of 10, there should be only 1 layer.

If you are like me, you print lots of small parts all at once. However, when one breaks away, you have to clear the plate, and start over.

Sprue was designed as a type of rafting, that was meant not as a raft, but as a model sprue, from those old plastic models we used to build.

So this does 2 things, connects the models together in an easy to dispose of format, and provide enough surface contact to keep your pieces down.

If you are using openscad, here is the formula.

y = 150; //Max Y mm
x = 260; //Max X mm
gapx = 10; //gap of x mm
gapy = 75; //gap of y mm
hscale = 10; //will scale down to 1mm.
vscale = 1; //will scale down to 0.01mm.
translate([-(xhscale)/2,-(yhscale)/2,0])
{
for (i = [0:gapxhscale:xhscale])
{
translate([i,0,0])
cube([1hscale,(y+1)hscale,1vscale]);
}
for (i = [0:gapyhscale:yhscale])
{
translate([0,i,0])
cube([(x +1)hscale,1hscale,1vscale]);
}
}As you can see, this is easy enough to modify.

This has had the benefit of holding my struts in place when I do lots of rafting, So I am at a win-win here.
