This kit does not fit the Neo V2
The ubiquitous Ender 3 Pro has been transformed into the Ender 3 V2 with 32 bit silent board, color LCD, improved belt tensioners, relocated power supply and a handy tool drawer!
Extend the capabilities of your Creality Ender 3 V2 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.
You can pair this kit with either a 400mm or 500mm Z height kit.
(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 Ender 3 V2 printer)
THIS KIT DOES NOT INCLUDE A BUILD SURFACE SUCH AS GLASS, PEI, OR STICKER SHEET
