Transform your Original Prusa MINI into the more powerful MINI+ with this official upgrade kit from Prusa Research. This kit elevates your printer's performance without the need to purchase a completely new machine. The core components of the upgrade include the improved extruder with a spring-loaded mechanism and the SuperPINDA sensor, which ensures faster and more precise automatic bed leveling. This significantly enhances print quality, particularly for fine details, aided by the new Z-axis belt idler system that reduces vibration. Noise levels have also been significantly reduced through optimized stepper motors and vibration dampers on the motors and idlers, making operation in a home environment much more pleasant. The build volume remains constant at 180 × 180 × 180 mm, yet offers more freedom for your projects due to improved reliability. Usability is enhanced by a revised LCD display and a more ergonomic user interface. The upgrade targets beginners looking to optimize their first printer, as well as makers who value professional results and low noise levels. Assembly is manageable even for technical novices thanks to Prusa's detailed instructions.
