We already announced that we will offer a lot more choices to Do3D users.
New 3D models will come with articulations (articulated joints), solid heads, and body pieces so you can print toys and statues. We can cut the space out in the head so that it can fit the articulated action figure body of your choice. DM or email info@do3d.com for more details.
3D mode is available here.
If need any particular toy head made now, contact info@do3d.com so we can pass your request to our modelers. Eventually all existing models we have on do3d.com will turn in to 3D printable toys!
