Convertible Pencil Rocket (Parametric)

Description

Update 12/1 - V1.1 See Below! When I Was A Kid And Bored In Class, I Used To Pretend My Pencil Was A Rocket Launching From My Desk. Now, Don'T Get Me Wrong Here -- I'M Not Trying To Squelch The Imagination Of Any Little Kids Who Dream Of Being Astronauts Some Day; I'M Just Trying To Help Those Pencils Fly A Little Straighter So They Actually Stick Into The Ceiling Like They'Re Supposed To. So What'S This "Convertible" Business All About, You Say? Well, That'S The Real Beauty Of This Design: When The Teacher Comes Walking By, You Just Set The Dart -- Er -- The Pencil Down On Its Fins And Explain That It'S A Space-Saving Pencil Stand. "Rocket Fins? No, Don'T Be Silly Ms. Fields -- It'S Just A Pencil Tripod!" This Is Not Intended To Turn A Pencil Into A Weapon Of Any Sort. That Said, I Bet This Would Probably Make A Great Weapon Of Some Sort. The Openscad File Is Parametric In Case You Need To Tweak The Sizes. I Fiddled With It Until It Sliced Nicely With 2-Layer-Thick Fins (0.5Mm Nozzle), And That'S How I Saved It. I Built It For The Venerable Ticonderoga #2. Even Though The Hole Is Hexagonal For The Pencil, The Parameter Specifies The In-Diameter Of The Hexagon, So It Should Work Just Fine For Round Pencils, Pens, Or Smooth Rod, Too. (Yes, That'S Reindeer Food In The Background Of The Photo.) This Is A Very Quick Print, And Would Make A Great Demo/Give-Away Piece -- Someone'S Bound To Have A Pencil Handy At Your Demo! Update 12/1/12: V1.1 You Can Now Specify An Angle For The Fins So That The Pencil Might Spin When It'S Thrown (Untested). The New Stl Has This Set At 5 Degrees For A Clockwise Spin For Right-Handed Throws.
