Why Use a Parametric Motor Mount Script? Designing a motor mounting plate from scratch every time you switch projects is repetitive and error-prone. A single wrong hole spacing can mean your NEMA 17 stepper motor won't fit. Our free script generates a fully parametric mount in seconds, based on standard NEMA 17 dimensions. Before You Start Make sure you have: - Fusion 360 installed and updated - Basic familiarity with running scripts via the Scripts and Add-Ins panel - (Optional) Our desktop app, if you want one-click execution instead of manual setup Step 1: Download the Script Head to the NEMA 17 Mount script page on FusioScripts and copy the Python code, or download it directly if you're using the desktop app. Step 2: Open Fusion 360's Scripts Panel 1. Go to Utilities → Add-Ins → Scripts and Add-Ins 2. Click the + icon next to "My Scripts" 3. Paste or import the downloaded script Step 3: Run the Script Select the script and click Run. A dialog box will appear asking for: - Plate thickness - Mounting hole diameter - Bolt circle spacing - Center bore diameter (for the motor shaft) Enter your values and click OK. Step 4: Review the Model Fusion 360 will generate the plate automatically. Check the hole alignment against your physical motor before printing or machining. If anything looks off, simply re-run the script with adjusted parameters — no manual redrawing needed. Step 5: Export Once you're happy with the design, export as STL for 3D printing or STEP/DXF for CNC machining. Common Issues - Holes misaligned: Double-check your bolt circle diameter matches your motor's datasheet. - Script won't run: Make sure you're using a supported Fusion 360 version and that the script file wasn't corrupted during download. Final Thoughts This script saves significant time for anyone building robotics, CNC machines, or 3D printers that use NEMA 17 motors.
