This is not for the Ender 3 Pro! This is the original Ender 3 (we call it the Non Pro).
Extend the capabilities of your Creality Ender 3 3D Printer to an impressive 400mm by 400mm printing platform. This modification kit includes all the frame, hardware, and build platform parts necessary to extend the printing capacity of the Ender 3. This kit does not increase the printer's height.
(Picture shows printer; printer is not included. This is for a DIY kit which includes frame parts, build plate and screws/nuts/washers to assemble onto your existing printer)
THIS KIT DOES NOT INCLUDE A BUILD SURFACE SUCH AS GLASS, PEI, OR STICKER SHEET
