OpenSCAD Bathtub Sailboat The hardest part of cranking out a Thing-A-Day for me is coming up with new ideas.  When I have an idea for a printable thing, I typically just design it, publish it, and get it out there on Thingiverse.  However, that means I generally don’t have many ideas left over for creating something new each day. Thankfully, I have my daughter.  After explaining that February was Thing-A-Day month and that I wanted to design something that was printable on our 3D printing robot, I asked her what she would like me to design.  A saildboat for the bathtub was her answer.  1 In many ways the challenge of coming up with something that will meet her arbitrary and completely unpredictable specifications is actually easier that thinking up an idea for something each day myself.  2 OpenSCAD Bathtub Sailboat by MakerBlock After explaining Thing-A-Day to my daughter, I asked her what she would like me to design for her for day 2.
