Dụng Cụ Giữ Đai Ốc Cỡ Nhỏ

I have placed a small Allen screw in the holder.
This allows me to hold a small nut or bolt.
The size of the nut is M0.8, so very small.
In the photo you can see the ratio to a grain of rice.
There is also a screwdriver version to make the set complete.

Glue the two parts together.
Drill the hole and tap the thread for the Allen screw.
Or drill the hole to directly place the Allen screw.
Place the bolt with some glue.
I use gel super glue, it fills and dries a bit more slowly, so that you can place / position the parts well together.

You need a small nozzle of 0.25 mm, with the Prusa printer it should not be any problem.
