Cross bar braces for the Creality Ender 5 Plus to stiffen up the frame a bit and lessen the top wobble caused by X and Y axis movement.

It reduced the visible wobble quite a lot on my printer.

Use any 8mm rod cut to 670mm +/- 5mm for the left and right. Max length is 678mm.
For front and back, 640mm +/- 5mm. Max length is 654mm.
The clamps are 30mm deep so you have some headroom.

Each clamp uses 6 M5 size screws. The 4 that attaches to the frame with M5 T-slot nuts requires 12mm screws of any type.
The 2 side mounted screws fits DIN912 M5 socket head cap screws with a minimum length of 12mm and a max length of 45mm, although 12-20mm is reasonable.
The backside fits DIN985 M5 lock nuts. Regular DIN934 M5 nuts will also work.

Note that there is a difference between the left and right, and front and back mounts as the frame is not completely square. Each are marked with a letter indicator for easy identification.

If you wish to mount the cross bar brace in the opposite direction as pictured, use the opposite side mount.

Total BOM:
2x 8x670mm rods
2x 8x640mm rods
32x M5 12mm screws
32x M5 T-nuts
16x M5 DIN912 screws between 12mm and 20mm (max 45mm)
16x M5 DIN985 locking nuts or DIN934 nuts.

Alternatively, 48x M5 12mm DIN912 screws if you don't mind the large head on the frame mounts.

My apologies for the old description not being as detailed as it could be.

Supports are recommended to support the sunken holes for the screw and nut but it might print fine without.
