I purchased an AnyCubic Photon resin printer.  The resin vat has a
groove on one corner to let you pour resin out, and while the top
surface is quite reasonable, the underside is not, so resin dribbles all
over the place.

I considered designing something to clip onto the vat to eliminate the
drips, but realized that I do not really know how to define that spout
shape.  I suppose it would involve a sweep of some sort.

Anyone have a suggestion?

Thanks!

Without knowing how the spout should look, it's very hard to give advice.

Some possible ways:

• Make a cone with cylinder(), hollow it out with difference() and anther
  cone.

• Start with a cube, difference out bits you don't want.

• Make 2D shapes and extrue or rotate extrude them

Either way, you'll probably have to add some attachment bits and remove some
bits you don't need.

If you could post some kind of sketch or picture, it would be so much easier
to give good suggestions.

the "idea" is as simple as this (and follows the usual rules for part
design):

1. model the vat
2. model some "nose" e.g. by playing around with cone shapes
3. difference the vat from the nose

e.g. see this code

// vat
height = 50;
width = 200;
length = 300;
rounded = 10;

spout();
#vat();

module spout()
{
difference()
{
nose();
vat();
}
}

module vat()
{
translate([length/2, width/2, -height])
linear_extrude(height)
offset(rounded)
square([length-2rounded, width-2rounded], center = true);
}

module nose()
{
r = rounded+5;
h = height;
difference()
{
halfcone(r, r-2, h);
rotate([0, 60, 45])
translate([-h/2, 0, -h/4])
cube(h, center = true);
}
}

module halfcone(r1=12, r2=11, h=40)
{
rotate([90, 0, -45])
difference()
{
cylinder(h=h-1, r1=r1, r2=.3r1, center = true);
cylinder(h=h, r1=r2, r2=.3r2, center = true);
translate([0, h/2, 0]) cube([h,h,h], center = true);
}
}
