Student Turaj developed a 3D printer named Studprint as part of the Hack Club Infill challenge, which offered a $350 grant for custom printer designs. The project was modeled in SOLIDWORKS and primarily uses classic LEGO bricks rather than Technic components.
The total cost of the build reached $173.35. Key electronic components include a BTT SKR Pico V1.0 control board, a Raspberry Pi Zero 2 W for wireless connectivity, and a Mean Well LRS-150-24 power supply, each costing approximately $25.
The device features five NEMA 17 stepper motors to manage the axes and filament feed to a Trianglelab V6 Extruder. LEGO pieces, including the build plate, account for $30 of the total budget.
The printer uses Klipper firmware to operate. In testing, the machine successfully produced a Benchy model in 1.25 hours, utilizing custom LEGO leadscrews for the printing process.
