Lego Technic Rubber Track Idler Wheels
Description
This Is A Set Of Idler Wheels For Use With The Lego Technic Rubber Tank Tracks. My Mindstorms Set Only Came With 4 Wheels And I Wanted To Have More Interesting Track Shapes Like Triangular Or Trapezoidal Tracks, So I Needed More Wheels. I Started Modeling The Standard Wheel, But Without The Teeth, Then I Made One As Small As I Could While Still Having The Clearance For The Inner Rubber Guide Row, Then I Made 2 Larger Wheels To Accommodate Different Needs. I Then Tried To Make The Outer And Inner Cog Teeth And I Managed To Create Something That Will Work With The Standard Gears.
