Lego Optimus Prime Welcome! This website features the transforming Lego Optimus Prime model you may have seen on YouTube. This model was designed by me, Andy Dufilie (A.K.A. fooblizoo), over a period of two weeks using only pieces offered by the Lego Factory website. Limiting the pieces as I have done allows anyone to purchase a copy of the model directly from Lego! Also featured below is another Lego Factory Transformer design of mine that you may be interested in. Buy this model! USD $41.31 + S/H 444 pieces (Buy using LDD instead.) Buy this model! USD $15.03 + S/H 141 pieces (No longer available) You can buy a model by clicking "View -> Send model to Lego.com" in Lego Digital Designer after you open one of the .lxf files available below.M Lego does not print out instructions for you -- you must download the .lxf file and use Lego Digital Designer to view the instructions. Press F7 in the program to view instructions. UPDATE: Lego Factory no longer offers the gray exhaust pipes, so I have replaced them with other pieces. The photos below still show the old version. UPDATE: Lego Factory no longer offers several pieces used in the robot car model. Building instructions are FREE! To view the instructions, you need to install Lego Digital Designer and open one of these files: Optimus_Prime_v2_Instructions.lxf fooblizoo_car_robot.lxf Scroll down to see videos and photos of these models.
