Printable parametric mold for oogoo feet for reprap printer

thingiverse

Create a printable parametric mold for casting rubber feet using oogoo. Use this for your Mendel90 reprap's base plate. The dimensions and settings are customizable, including the number of spokes in the foot and the number of molds in the printed part. The example STLs are for single and multiple mold castings for 3mm screw and 10mm washer-fixable feet. Oogoo is easy to use; learn more at http://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/. As this is your first OpenSCAD design, a first oogoo project and a published print with your new reprap, be gentle in your critique. Print the mold using PLA on your 3D printer with these settings: 0.4mm layer thickness, single perimeter, one bottom layer, one top layer, and rectilinear infill at 25%. Use one or two tablespoons of oogoo for each foot when mixing (as the mold is small). For a fast-setting oogoo, use a 1:1 silicone to starch ratio (instructions can be found at http://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/). Color the oogoo with oil paint as desired. Press the oogoo into the mold quickly, using a popsicle stick to help. Scrape off excess oogoo from the top of the mold. Wait for the oogoo to set (about 30 minutes), then carefully remove the foot from the mold with a toothpick and trim any excess rubber with scissors if necessary.
