Summary

Simple idler pulley for OpenSCAD. Inspired by a script Rick at Makergear.com wrote. This script is convenient because you can change the belt width and the overhang angle along with the lip height and thickness.

Licensed public domain cause reprappers are chill bros and chicks.

Instructions

The STL is probably too big to be useful but it has a belt width of 10mm, ID of 20mm and OD of 30mm.The overhang is set to 50 degrees. I am just using it to generate a preview thumbnail for people to see.

Here is a preview of the variables used...

//variables (mm)
idlerID = 20;
idlerOD = 30;
beltwidth= 10;
$fn=30; //faceting

//these are the lips that hold the belt on
lipheight = 10;
lipthickness = 4;
topangle = 60; //the angle the top lip overhang makes. You can increase this to lower the idler profile.

Hi, this is really great, thanks a lot. There is a bug in the code, though, which makes the beltwidth too wide. In the the lines below, you shouldn't multiply lipthickness*2

    translate([0,0,lipthickness*2+beltwidth+lipheight*cos(topangle)])cylinder(r=lipheight+idlerOD/2, h=lipthickness);

    translate([0,0,beltwidth+lipthickness*2])cylinder(r1=idlerOD/2, r2=lipheight+idlerOD/2, h=lipheight*cos(topangle));
