He began with the tentacles, since they would determine how big the main body would have to be. To get started on this project, Reg Taylor, a freelance mechanical engineer currently based in France, watched all three Matrix films three times before deciding on designing a sentinel, as it would be one of the most achievable Matrix objects to replicate in a realistic and detailed way. The sentinel is assembled out of over 500 3D printed pieces, and took a total of 241 hours in building time to create. Now, it’s possible to 3D print a beautifully realistic, fully articulated model at home thanks to Reg Taylor’s downloadable design.īefore getting started, however, you might want to make sure you’ve got time and patience. Their squid-like tentacles and ability to glide effortlessly through the air, as though they were actually underwater, made for the one of the most memorable fight scenes in the first Matrix movie.

In the sci-fi universe of The Matrix, sentinels are the menacing, autonomous killing machines that roam the ancient sewers and passageways of dead human cities in search of defenseless human beings.
