yf-12 3D print model

1:1 print as 1:144 scale mode or depending on the 3D printer adjustment ratio,

The positioning shaft can use a bamboo stick of appropriate size,

Stl files do not need to be processed, just slice them directly.

I made the mold parting for a FDM printer(render in blue).

A resin-printed version is also available(render in yellow). It can use blender3d to divide the model into small parts.(https://www.youtube.com/watch?v=4cvnNYGuRlA)
