Z braces for Wanhao Duplicator i3, Cocoon Create, Maker Select, and Malyan M150 i3 3D printers.

This kit will add rigidity to your printer, giving you better prints more often.

Does it work and is it worth doing?
Just see maker zsonybrasco's before & after shots:

Here is a good, and short, article on 3D printer rigidity:

To compliment this mod, have a look at my Z Extensions:

(For an additional 37mm of Z clearance)

BTW...
This design was powered by beer... just like lots of hobbies... so if you like this design and you'd like to buy me one... or two...

A huge THANKS and CHEERS to those who've already shouted.

This design uses two 8mm or 5/16" threaded rods. The rods lock at the bottom and have adjustment at the top. These rods brace the Z axis towers, to the front of the Y axis, keeping them vertical and square to the build plate.

There are also two braces for the Y-axis, front and rear. These enable the Y belt to be tensioned correctly by stopping the Y motor torque from pulling the frame ends together.


No need to drill any new holes in the printer, but you do need to replace some short 3mm screws for longer ones (10mm). The short screws are reused for the Y braces.

See "Instructions" below for further detail.

Our friends over at "3D Printer Wiki" have also put together a build guide for this…
