LEGO BUGATTI CHIRON servo_motorized

thingiverse

Hi everyone! This year, I purchased and constructed a LEGO BUGATTI CHIRON: a fantastic model consisting of nearly 4000 pieces from LEGO TECHNIC. However, as any builder knows, the response from technicians at LEGO is always the same: "There isn't enough space for an electric motor!" Still, I discovered a small gap in front of the CHIRON engine near the gear that goes down to the gearbox. After measuring it, I confirmed there's enough room for a 12g servo! To get continuous rotation from the servo, you'll need to hack it. Search online for "servo hack" or visit instructables.com. Using 123D Design, I created a custom servo mount and designed a special pinion that attaches to the servo. Additionally, you'll require a 20-tooth pinion; I've included an STL file in case you don't have it in stock. You can find it on thingiverse by searching "Lego_Technic_Parts." The servo mount can be printed with or without the opening for the servo cable. However, to accommodate the cable, you'll need to cut a slot into the side of the mount. Finally, just plug the servo into a servo tester (watch this video below to see it in action!).
