Description
#### Featured In These Youtube Videos: - Demonstration And Backdriving Https://Youtu.Be/Tt3Bznsqmb0 #### Print Settings! - You Must Use Supports To Print Some Of These Parts, It Was Really Unavoidable. - If You Wish To Back-Drive This, You'Ll Need To Use At Least -.05 Horizontal Expansion Setting ####This Looks Familiar! - This Gearbox Is Scaled Up (150%) From The Size Used In The Robotic Arm Project, But It Doesn'T Work The Same Way So Its Incompatible Even If It Was Scaled Back Down. ####Assembly - Print The Planets With A Raft, They Will Print In The Right Alignment. Leave The Raft On Until The Gearbox Is Assembled. Place The Sun Gear Inside The Planets, And Put Ring Gear #2 On. Place A Ring Closure On Ring #2 And Then Install All The Other Ring Gears. #####How It Works - When The Sun Gear Is Turned, Ring Gears #1 & #4 Will Be At The Same Potential And Ring Gears #2 And #3 Will Rotate Opposite To Each Other. #### Other Important Info: #####Cad Files?? - I Included The Fusion 360 Project With This, But The Most Recent Version Of This Project Can Be Downloaded In Lots Of Different Formats From This Link: Http://A360.Co/2Kwxprn - Feel Free To Create Your Own Modifications And Parts For This Project, And If You Do, Make Sure You Create A Remix And Upload Them, Then I'Ll Add Them To My Main Collection So The Whole Community Can Share Them!
