3D model description

*PLEASE NOTE! this design requires modifications.

Before you start, read the whole description and make sure you can do it.

I couldn't find any "Pull Rod" kits on the market for the Creality Ender 3 S1 Pro printer, so I decided to make one.

This design stiffens the frame of your printer to reduce vibration.

I noticed that when increasing speeds with Klipper, the top of the printer moves a lot and creates vibrations on my prints (especially on the Y-axis) that I was unable to correct with the resonance compensation.

This is further accentuated if you have weight on the top of the printer frame (filament spool, Sonic Pad, filament dryer...).

I decided not to place the threaded rods on the corners at the front of the printer to leave the tray more accessible and room to mount other elements in the corners like a screen, camera, tool holder...

Camera support: link

Tool holder : link

Adaptation information:

On the right, the bottom bracket fits over the screw location of your original control screen bracket. So you will have to move it for example with my design that you can find here: link

On the left, for the bottom support, you need to drill two holes in the fairing and the extruded aluminum profile and tap them in M4 (see photo) at the same location as on the right side where there is the screen.

Make sure you have the tooling to make this modification or you can also place the part with tape and screw it only in the plastic of the fairing.

If you want the maximum rigidity I think the ideal is still to attach to the aluminum profile of the chassis.

The maximum print height can be decreased by a few millimeters.


Choose a rigid material, I used PETG.

Place the pieces on your tray like in my picture with brackets only in the two screw holes that are against the tray.

To get a stiff piece, I printed with three perimeters and a 25% grid fill.

Material for assembly:

  • 2x M8 threaded rods 500 mm long (minimum 490 mm)

  • 8x M8 nuts

  • 8x M8 washers (maximum outer diameter 16 mm)

  • 4x M4 x 30mm screws (you can get the 3 screws from the screen + 1 extra that comes with your printer)

  • 2x M5 x 10mm screws

  • 2x M5 x 20mm screws

  • 4x T-nut M5

3D printing settings

PETG or other strong filament (rigid)

0.4 mm nozzle

Layer thickness 0.16 mm

3 perimeters

Filling 25% grid

Positioning the pieces on the tray, according to the photo, supports only in the two screw holes that are against the tray.
