# Build a Jigsaw puzzle for Lasercutting.
|
|
# User defines:
|
|
# - dimensions,
|
|
# - number of pieces in X and Y,
|
|
# - notch size,
|
|
# - random amount of perturbation for uniqueness,
|
|
# - border and rounding for border and inner corners
|
|
# - random or random seed for repeats
|
|
|
|
### 0.1 make basic jigsaw for lasercut - March 2011
|
|
### 0.2 add random seed so repeatable, add pieces for manual booleans - May 2011
|
|
### 0.3 add some no-knob edges - June 2019
|
|
|
|
### Todo
|
|
# add option to cut pieces:
|
|
# - taking two rows(cols) at a time - reverse the second one and concat on end - add z to close
|
|
# - taking a row and a col - do intersect = piece.
