Open/Closed Sign

Description

Inspired By Ikeda Yosuke'S Open/Close Sign Design Which Relies On Gravity And Relatively Frictionless Joints, I Decided To Design One Using Planetary Gears To Drive The Movement Of The Letters. An Animation Of The Transition Can Be Seen Here: Https://Youtu.Be/Tmrulpgojly <I>The Model Has Now Been Updated To Include The "D" In Closed But The Video Is Of An Older Version.</I> The Gears Are Made To Snap Fit Onto Their Respective Axles, Tolerances For Rotational And Press Fit Parts Have Been Confirmed And Should Work Well With A Properly Calibrated Printer. <B>Updated 24/3/17:</B> - D In "Closed" Has Finally Been Added To The Design. Using The Joiner.Stl Piece, The Letter D Should Lay Perfectly Over The Top Of The C And The L. First Glue The Joiner To Your Gear_Right In The Correct Position And Then Glue It To Your Letter D To Allow Proper Alignment. - Type Has Been Refined A Little Bit, Particularly On The Letters E, D, C, And L. <B>Updated 11/2/17:</B> - Registration Points Added For Letters To Attach To Gears - Split Base Plate For Smaller Build Platforms (Minimum Build Size Required 160 X 160 Mm) - Refined Font To Remove Sharp Edges - E And S/N Has Been Chamfered On The Bottom Edge To Avoid Catching - Planet Gears And Gear_Left Have Been Heightened By 1Mm In Order Avoid Contact With The Axle - Gear_Left Has Modified Gears To Only Allow Rotation In The Direction Such That Letters Don'T Touch Each Other (Idea By Frankvdh)
