# Splendor organizers to fit in Splendor box

# This makefile expects an OpenSCAD file named $(PREFIX).scad that defines
# the following variables:
#
# PART -- the name of a part to generate
# VERBOSE -- logically true if you want verbose output (optional)
#
# The OpenSCAD program should have logic that renders a single part by name:
#
# if (PART == "foo") {
# foo();
# } else if (PART == "bar") {
# bar();
# } else if (PART == "foo-bar") {
# foo_bar();
# }
#
# This makefile will use OpenSCAD to create individual model (STL) files and
# image (PNG) files for each declared part, and will use Slic3r to generate
# G-Code for each declared part.
#
# So if PREFIX=widget, then the created files will be:
#
# stl/widget-foo.stl stl/widget-bar.stl stl/widget-foo-bar.stl
# png/widget-foo.png png/widget-bar.png png/widget-foo-bar.png
# gcode/widget-foo.gcode gcode/widget-bar.gcode gcode/widget-foo-bar.gcode
# OpenSCAD binary and options
OPENSCAD=/usr/bin/openscad
OPENSCAD_OPTIONS=-DVERBOSE=false
IMAGE_OPTIONS=--imgsize=1024,768 --colorscheme=DeepOcean
# Slic3r binary and options
SLIC3R=/opt/Slic3r/latest/slic3r
SLIC3R_INI=slic3r.ini
SLIC3R_OPTIONS=--load $(SLIC3R_INI) --print-center 125,105
