Printed some other multi-purpose mounts for this and they simply didn’t fit. The angle was wrong for the threaded rod and the nuts were fastening at an angle and the 4mm fasteners were too weedy…

…so I designed a new one.

There are no stupid printed plastic fasteners with this kit. Why would you print when metal ones are cheap and better?

The brace is only to stop vibration. Do not overtighten or it will pull your frame out of whack and you’ll get bed levelling grief.

It may fit other Creality and Hictop models but I haven’t tested. If it fits your printer then please leave a positive comment.

I've tested this and it does not limit movement in any direction.

Enjoy…

You need:

4x prints of this file
8x M5 cap head Allen screws (16mm).
8x M5 T-nuts
2x 68cm lengths of M8 threaded rod
8x M8 nuts (Nyloc optional)
8x 8mm flat washers

EDIT 2nd March 2018

Before fitting a frame brace, first consider whether or not you actually need one. The objective is to reduce vibration and improve the quality of very tall prints.

At the moment I'm trying to print small objects on a cold, snow-bound conservatory. When I turn the heating on the bed levelling changes massively. Why is that?

It's because the aluminium frame is now braced with a steel rod and the two have totally different thermal expansion characteristics. So much so that I'm going to remove the brace until the weather warms up at bit.

SMALL RANT: It seems to me that there's a lot of poorly conceived but pretty printer upgrades that people make but don't actually improve anything. Squash ball feet are a good example. These don't eliminate all vibration - they shift the resonant frequency - and on my old printer they made the prints much worse because the carriage was moving one way when the chassis was rebounding another. Think before you print before you build...
