The little brother to the Xtender 400, this version sports a medium sized build plate of 12 inch by 12 inch (approximately 300 by 300mm).  When you want just a little more room on the build platform but don't have space for the Xtender 400.

Note: This model includes the same, but smaller, parts as the Ender Xtender 400.  If you need a print surface, we suggest adding the 12 by 12 mirror product to your order so we can ship it in the same carton.

(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 printer)

 NOTE: You are changing the build size of your printer.  You will most likely need to update your firmware.  If you do not know how to do that, then please learn that process before building this kit.  Ender Extender is not responsible for your ability or inability to update your machine's firmware.  There are a ton of resources online to guide you through that process.

Installation Guides



The aluminum plate that comes with this kit is not warrantied to be flat. You will require either a glass build surface or a bltouch; both are actually strongly recommended.
