Step 1: Tools and Materials:
Hot glue gun
#4 finishing washers
5mm diameter spherical magnets
4mm diameter hardwood dowels
Step 2: Print the Parts.
Step 3: Cut the Dowels.
Test fit the dowels in the arm joint holes. Don't force the dowel into the holes, as this may cause the plastic pieces to crack. If necessary, sand the ends of the dowels until they fit properly.
Put a dab of hot glue into the holes and insert one end of each dowel piece into the arm joints.
Repeat these steps for the wrist joints.
Step 4: Glue on the Finishing Washers.
Squirt a bead of hot glue around the edge of the cylindrical recess and firmly press a finishing washer into the glue.
Repeat these steps with the remaining pieces.
Step 5: Glue on the Magnets.
Align the poles by placing the magnet in the bowl area of one of the finishing washers. I like to use the leg pieces for this.
Put a dab of hot glue into the hemispherical recess of one of the pieces. With the magnet still in the leg joint, press it firmly into your glue blob and hold it until the glue has cooled enough to keep the magnet in place.
Make sure the joint functions, and repeat these steps with all of the remaining joints.
Step 6: Davincibot! Assemble!
