Introduction: Davincibots: Create a 3d Printed Modular Robot Toy.

Click on the first image, to start a slideshow to introduce Davincibots.

Step 1: Tools and Materials:

Tools used:
3d printer
Hot glue gun
Small saw

Materials needed:
Plastic
#4 finishing washers
5mm diameter spherical magnets
4mm diameter hardwood dowels

Step 2: Print the Parts.

Download the files, found here, and print up the parts.  If you don't have a 3d printer, you might be able to find a local makerspace that will let you use theirs.  You can also order prints from a service.

Step 3: Cut the Dowels.

Cut two 2cm lengths of the 4mm diameter 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.

There should be a cylindrical recess to house the finishing washers on each piece that will accept them.

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.

In order for the Davincibot to have its awesome poseability, you must glue the magnets on correctly.  Even though the magnets are spherical, they still have poles like a bar magnet.  If the poles aren't aligned properly, the joints won't connect the way they're supposed to.

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!

If everything worked out, you should have a pile of robot parts.  Put them together!

Step 7: Make Me, Share Me, Trade Me, Tell Your Friends.

Once you've made one Davincibot, make another!  Sell them!  Trade them!  Tell your friends!

Step 8: Make an Upgrade.

Now make an upgrade!

Like a bazooka!

Or a Gatling gun!

Or design your own and post it to thingiverse!

very cool, so can you replace and arm with a leg and turn him to a mutant-bot?

Yeah, you can interchange the extremities however you choose, so long as they fit.
