This is just a screw. M30 bolt and nut.
I designed the dimensions as close to the real thing as possible.
What is characteristic is that I add a small hole which passes a string and a small washer that is same size as bolt and nut. It is cute.
I would like washers to be made in various colors.
I want you to play by spinning around and hanging.
SUNLU ABS, PLA
To make the screw rotate smoothly, I adjusted "Internal Compensation" to 0.5mm.
To make the screw a bit heavier and more robust, I adjust "Shell Count" to 8.
