Original Prusa i3 MK3S/+ to MK3.5S Upgrade Kit 

The i3 MK3S/+ to MK3.5S Upgrade Kit contains everything you need to fully upgrade your i3 MK3S / MK3S+ printer to MK3.5S

Note: 
Prusa provides no upgrade path from the MK3.5S to the MK3.9S or MK4S. This means if you later decide to upgrade to the MK3.9S or MK4S, you will need to buy the full MK3S/+ to MK3.9S or MK3S/+ MK4S upgrade kit.

 Important:  
1) PETG printed parts are NOT included. Please print them before you disassemble your MK3S/+ (The filament is included in the upgrade package).
2) The black injection-molded spool holder is not part of the upgrade package.
3) This upgrade is supplied as a kit - you will need to assemble it yourself.
