How I printed: In CURA 1 turn off enable retraction option 2 Fill density 100% 3 print speed 45 (mm/s) 4 print temperature 180 My printer is RepRap from the MOST Athena Printer http://www.appropedia.org/Athena_Build_Overview I use PLA red 1.75mm ( the real diameter is 1.94 mm) How I create: I download the bird image from https://s-media-cache-ak0.pinimg.com/236x/ae/04/71/ae0471d53045c767e89caaee65ae0d2f.jpg. I use Inkscape to convert 2D cat image to generate path to openSCAD. I use openSCAD to design light switch plate with Key Racks. I open cat.SCAD file in openSCAD and then copied all the code and pasted them into my light switch plate with Key Racks. I use Inkscape to convert 2D image to generate path to openSCAD. The problem is installing the software. My laptop is Mac. I downloaded the Inkscape software from https://inkscape.org/en/learn/books/ I need to download XQuartz software from https://www.xquartz.org/ To use the function OpenSCAD converter from Inkscape, I need to add these two files into Inkscape extension folder from http://www.thingiverse.com/thing:25036 In Mac, these files are hidden. I need to use terminal to find these files and then move them to Inkscape folder by using these commands. mv paths2openscad.py ~/.config/inkscape/extensions/ mv paths2openscad.inx ~/.config/inkscape/extensions/
