Upgrade from BondTech MK2.5 / 3 to MK3S
This Rebuild Set contains only the parts needed to upgrade the previous Bondtech Upgrade Kits for Prusa i3 MK2.5 / 3 to the MK3S design.
The MK3S upgrade was necessary as the Prusa i3 MK3S has a new built-in IR filament sensor that does not match previous Bondtech designs.

To use the kit, the Prusa Upgrade Kit for MK3S is required!
Do not buy this product if you have not upgraded your Prusa i3 to MK3S.

There is also a new X-Carriage design that will properly lay the new IR filament sensor cable. You can also download the STL files and print them yourself.

The new IR filament sensor and Prusa cable are not included.

The most popular technology used for 3D printing is FDM (Fused Deposition Modelling). A heated nozzle (hot-end) melts the plastic wire, layering the melted parts.
