Prusa MK 3S 3D Printer I bought this a few years ago as the MK3 and then converted it to the MK3S when the upgrade kit came out. Kit includes -3D printer -Enclosure: -Dimable lights -Temperature Controlled -clear removable front -4 spool holders on top -Concrete block for vibration dampening -PSU has been moved outside the enclosure as that is more vulnerable to the heat. It can easily be pulled off when the printer is taken out for a more portable setup -Spare Parts: -Nozzles: 2x0.4mm, 1x0.4mm Hardened Steel, 1x02.mm, 1x1mm -New stainless rods and bearings -Another set of all 3D printed parts for printer -powder coated bed -smooth PEI bed with extra sheets -Maintenance tools
