Parametric Crowned Pulley
by johnr, published
A parametric crowned pulley, inspired by DaleDunn's.
I liked this idea over the flanged bearing covers, but I couldn't get a bearing to fit the original and thought it wasn't wide enough. With no access to SolidWorks I figured I'd redo the thing in OpenSCAD.
The second photo shows the size difference between DaleDunn's and mine.
Print as is, or adjust to your liking/needs.
