This is the 3D printed version of the Rose Acros top cap.

It fits to the Rose Square stem. Which is used for example at the Rose Backroad Gravelbike.

I made this from PA12CF15.

I printed this with a layer height of 0.05mm, so you can't see any layers and don't notice that this is 3d printed.

Printed on a structured print plate, it looks better thand the original.
