Reinforced part to fix the "Nema 17" motors of the Z axis on Creality Ender 3 S1 and S1 PRO printers as well as for other printer models that use a 40/20 aluminum extrusion profile.

I created this reinforced part because the original ones on my printer were cracked at the screws.

It is thicker and more rigid, which allows a better support of your motor.

You can use the original screws of your printer.
For the S1 and S1 Pro which already have the aluminum profile drilled for the screws, use the "Z motor support extrusion center" design.
It allows an installation without disassembling the two uprights of the printer.

For other types or brands of printers, you have the possibility of mounting the support in the extrusion profile or with metal T-nuts.

Choose a filament that is resistant to temperature such as PETG, ASA, ABS... because the motors heat up.
