Elegoo Centauri Carbon Spool Holder

I made this for the Elegoo Centauri Carbon. The large bolt and nut hold the filament spool centered due to its conical shape. The other lever mechanism attaches to the device itself. The locking mechanism contains a 5M nut, M5x20 bolt, and 8x25mm a spring. I placed them in the step file that way so you can see how the assembly is done. . I made the pin in the locking mechanism from metal. If you want, you can create a hole in that part via the 123dx file and use a 3mm diameter shaft. When printing the large nut, you should set the x-y hole compensation to +0.2mm, and the x-y contour compensation to -0.2mm for the bolt. Otherwise, the bolt and nut will not fit together easily. you can watch to how works. https://youtu.be/lMnzDwG-Thc
