|
|
// Description: Creates a mask to use when making NEMA 23 stepper motor mounts.
|
|
// Arguments:
|
|
// depth = The thickness of the mounting hole mask. Default: 5
|
|
// l = The length of the slots, for making an adjustable motor mount. Default: 5
|
|
// slop = The printer-specific slop value to make parts fit just right. Default: `PRINTER_SLOP`
|
|
// orient = Orientation of the stepper. Use the `ORIENT_` constants from `constants.scad`. Default: `ORIENT_Z`.
|
|
// anchor = Alignment of the stepper. Use the constants from `constants.scad`. Default: `CENTER`.
