Ball mount 20mm

thingiverse

This is a Ball Joint Mounting System with One Screw Attachment. The ball joint is designed to securely hold a flat object in place using one screw. The ball is attached to the screw and the socket can rotate or tilt freely around it. Assembly requires 4 M5x20 screws for the plates, 4 M5 nuts to sink into the bottom plate, 1 M5x30 or longer screw through the ball, and 1 M5 nut or plastic tube to counter the long screw on the ball. Additionally, doublesided adhesive tape (or other glue) is used to mount a mirror or object. A flat or hex screwdriver, matching the screws used, is necessary for assembly. The four screws in the plate squeeze onto the ball, allowing adjustment of the force needed to move the joint. Spacers can be inserted between the plates for a very loose joint. Printer Settings: * Printer: Tinyboy Fabricator * Rafts: Doesn't Matter * Supports: No * Resolution: 0.1mm * Infill: 25% Notes: The ball is available as one piece or two halves. If your printer produces a deformed ball in the overhang area, printing the two halves and gluing them together may be preferred. Glue is not necessary, however, as the center screw will hold the parts firmly. The tube.stl piece is for demonstration purposes only. It makes the center screw disappear inside plastic, making it look nicer. For a real mount, a shorter spacer tube and long center screw are recommended. Design: This model was created using FreeCAD 0.16 with Part Design and Part Workbenches. The design is built from classic primitives: cube, cylinder, sphere, cone, with difference and union operations. It is a fully parameterized tree of primitives, allowing for easy editing of dimensions and updates to the parts. Exceptions include Camfer and Fillet on top and bottom plates, which produce independent parts that can be modified by deleting them from the Model tree and redoing the camfer or filleting as needed.
