thingiverse
This is a fully scalable design for GT2 timing pulleys. Users have the ability to edit the *.FCStd file within FreeCAD to create custom GT2 pulleys. Step 1: Download "Pulley v1.FCStd" Step 2: Open the file in FreeCAD, which can be downloaded from https://www.freecadweb.org/ and installed for free if it is not already on your computer Step 3: Double-click on the spreadsheet icon in the tree on the left-hand panel of FreeCAD to customize the values. The cells for "Number of teeth", "Belt width" and "Shaft diameter" can be edited, as they are highlighted in blue color in the image attached. Editing any other cell may break the relationship and produce useless results. Recommended shaft diameter-number of tooth relation: The number of teeth must be at least three times greater than the shaft diameter Users can also add fastening holes or keyways to the pulley. Pulley.FCStd: A potential error in the sketch plane occurs when the shaft diameter exceeds a certain limit Pulley v1.SCStd: The error has been corrected (Dependencies were deactivated)
