Creating a Custom Motor Mount with Boolean Cut in FreeCAD
00:00:01 Objective: This tutorial demonstrates creating a custom motor mount in FreeCAD (v1) using the Part Design Boolean cut feature.
00:00:10 Method: The process involves first creating a "fake motor" template body that defines the shape and size of the actual motor. This template is intentionally made slightly oversized to ensure proper fitting clearance (tolerance) in the final mount.
00:01:10 Creating the Fake Motor: The template starts with a sketch on the XY plane (30x25mm centered rectangle with 10mm radius fillets) which is then padded (30mm).
00:02:46 Adding Motor Detail: Further details are added to the motor template, including sketching features on the back (another filleted rectangle R9.5mm, a cut-out shape made with Polyline and Trim tools) and padding them (6mm).
00:07:38 Motor Axle Creation: The motor axle is modeled by sketching and padding its base/shielding (7mm diameter circle, padded 2mm) and the axle itself (2mm diameter circle, padded 10mm) on the front face.
00:09:02 Finishing the Template: Fillets are added to the motor body edges (5mm and 3mm). This completed template body is named "Motor Body".
00:10:03 Starting the Mount: A new, separate body is created to model the actual mount (named "Mount"). The tutorial employs top-down modeling principles.
00:11:37 Linking Geometry (Top-Down Design): The Subshape Binder tool is used to reference specific edges from the "Motor Body" into the active "Mount" body. This creates a parametric link, so changes to the motor template can automatically update the mount.
00:13:24 Mount Base Sketching: A sketch defining the mount's main shape is created. It uses the External Geometry tool to reference the linked edges from the Subshape Binder and is dimensioned to slightly intersect the motor template area (e.g., -1mm offset from a linked edge).
00:16:37 Building the Mount Base: The mount sketch is padded (10mm thick, ensuring the direction is correct, possibly reversed).
00:17:02 Adding a Support Brace: To strengthen the mount, a support brace is added by creating a new sketch on a side face, positioning it (Z=20mm), sketching its profile (using Polyline, symmetry, angle 150deg, lengths 15mm & 3mm), and padding it symmetrically (12mm total width).
00:20:40 Tolerance Necessity: It's highlighted that for the Boolean cut to create a functional cavity, the "tool" (the fake motor shape) must be slightly larger than the physical motor to provide clearance.
00:21:02 Scaling with Draft Clone: The Draft Workbench Clone tool (distinct from the Part Design Clone) is used to duplicate the entire "Motor Body". This specific clone tool allows scaling.
00:22:14 Applying Scale Factor: The created clone ("Motor Body Clone") is selected, and its Scale property in the Data tab is adjusted (e.g., to 1.02 for X, Y, and Z) to make it slightly larger than the original template.
00:23:30 Using Base Feature: Since the Draft Clone exists outside the Part Design body structure, the Base Feature tool is used. By selecting the clone and creating/selecting a new Part Design body ("Tool Body"), the scaled clone geometry is linked into the Part Design workflow, making it usable for Boolean operations.
00:24:25 Performing the Boolean Cut: The main "Mount" body is made active. The Part Design Boolean Operation tool is selected. The "Tool Body" (containing the scaled clone link) is added to the operation, and the type is set to Cut.
00:25:05 Cut Result & Troubleshooting: This subtracts the slightly oversized motor shape from the mount, creating a cavity with built-in tolerance. A potential issue (multi-solid error) and its fix (setting Allow Compound to True on the body) are mentioned.
00:26:29 Finalizing the Mount: Standard Part Design features are added to the finished mount, such as sketching mounting holes (2.5mm diameter, positioned 3mm from edges) and creating through-cuts using the Pocket tool.
00:29:07 Key Techniques Learned: The tutorial covers creating template bodies, using Draft Clone for scaling to add tolerance, linking geometry between bodies with Subshape Binder, incorporating external objects into Part Design via Base Feature, and executing Boolean cuts for creating custom-fit parts.
