I’ve already built a prototype before this version, but the results were well…mediocre,” William wrote of the project. “My first project is this Lego Mindstorms 3D printer. Some of the notable tweaks from the first prototype were creating a racked track for the X and Y axes to enhance printing precision, as well as modifying the extruder for efficiency. When he set to work a few months after the initial version, William knew the areas he wanted to focus on for improvement. However, it’s not very precise and won’t print anything useful,” and made sure to point out that it was “still cool though.” When he posted a video of the first iteration, he noted that this 3D printer is “easy to build and to program. This DIY 3D printer is built from Legos, and version 2.0 has a leg up on its predecessor, per William’s description. Really, this design is already his second iteration of his design, as the first “was a prototype and the result wasn’t that great.” I’m glad to see he reworked his homemade 3D printer and is now at a sharing point, as this design clearly has solid potential as he continues to work it further and now has opened it up for feedback from the Instructables community. William, who has a penchant for all things robot, maintains a YouTube channel devoted to his Robot Friends.

Instructables user William ( W1ll14m) has just posted his first contribution to the design-sharing site, and it’s a very impressive initial creation. Every maker remembers his or her first build as a monumental achievement, and a viable springboard for them to dive deeper in and hone their skills. Everyone has to start somewhere, they say - and that’s especially true for those in the maker movement.
