Snap-together joiners

These joiners are useful for making snap-together parts.

half_joiner_clear()

Creates a shape used to clear a volume to prepare to place a half_joiner() or half_joiner2()

Arg	What it is
h	Height of joiner.
w	Width of joiner.
a	Overhang angle of joiner in degrees. (default 30)
clearance	Extra side clearance for joiner. (default 0)

Example:

difference() {
    cube(size=50, center=true);
    half_joiner_clear(h=50, w=10, clearance=2);
}

half_joiner()

Creates a joiner shape that is designed to mate with a half_joiner2() shape.

Arg	What it is
h	Height of joiner.
w	Width of joiner.
l	Length extended from the back of the joiner.
a	Overhang angle of joiner in degrees. (default 30)
screwsize	Size of screwhole through the joiner. (default none)
guides	If true (default), add guides to center mating of joiners.
slop	Slight adjustment spacing to allow for vagarities of various printers.

Example:

union() {
    difference() {
        cube(size=50, center=true);
        half_joiner_clear(h=50, w=10, clearance=2);
    }
    half_joiner(h=50, w=10, l=10, screwsize=3);
}

half_joiner2()

Creates a joiner shape that is designed to mate with a half_joiner() shape.

Arg	What it is
h	Height of joiner.
w	Width of joiner.
l	Length extended from the back of the joiner.
a	Overhang angle of joiner in degrees. (default 30)
screwsize	Size of screwhole through the joiner. (default none)
guides	If true (default), add guides to center mating of joiners.
slop	Slight adjustment spacing to allow for vagarities of various printers.

Example:

union() {
    difference() {
        cube(size=50, center=true);
        half_joiner_clear(h=50, w=10, clearance=2);

Example:

difference() {
    cube(size=50, center=true);
    joiner_clear(h=50, w=10, clearance=2);
}

joiner()

Creates a joiner shape that is designed to mate with another rotated joiner() shape.

Arg	What it is
