Ball mount 20mm

thingiverse

This is a ball joint to mount a flat object with one screw. The ball is on the screw, and the socket can rotate or tilt freely around the ball. Assembly requires 4 screws, M5x20 for the plates 4 nuts, M5 to sink in the bottom plate. 1 screw, M5x30 or longer through the ball. 1 nut M5 or the plastic tube to counter the long screw on the ball. doublesided adhesive tape (or other glue) to mount a mirror or whatever object you want to mount. Flat or hex screwdriver, matching the screws you use. The 4 screws in the plate squeze on the ball. Use them to adjust the force that is needed to move the joint. Insert spacers between the plates, if you want a very loose joint. Print Settings Printer: Tinyboy Fabricator Rafts: Doesn't Matter Supports: No Resolution: 0.1mm Infill: 25% Notes: The ball is available as one piece, or as two halves. If your printer produces a deformed ball in the overhang area, you are probably better of printing the two halves and glue them together. Gluing is actually not necessary, the center screw will hold the parts firmly. The tube.stl piece is only for demonstration purposes. It basically makes the center screw disappear inside plastics, so that it looks nicer for demonstration purposes. For a real mount, you probably want to use a shorter spacer tube, and a long center screw. How I Designed This FreeCAD 0.16 - Using only Part Design and Part Workbenches. This is completely built from the classic primitives, cube, cylinder, sphere, cone, with difference and union operations - without using any sketches. It is a fully parameterized tree of primitives. You can edit dimensions and see how the parts get updated. Exceptions: Camfer and Fillet (on top and bottom plate) produce independant parts. If you want to modify these, delete them from the Model tree to expose the original plate_top or plate_bot part, then edit the primitives and dimensions as needed, then redo the camfer of filleting, if needed.
