IKEA handle HISHULT

I recommend printing the body from Prusament ASA Natural. 
You can achieve a great “ceramic” surface by smoothing the model. 

Article about smoothing can be found here: https://blog.prusa3d.com/improve-your-3d-prints-with-chemical-smoothing_36268/ 

To print the cap, I recommend the Colorfab COPPERFILL material, which can then be burnished to give a nice copper look.

The model is designed to use an M3 screw for mounting.

The cap should fit perfectly into the body.

This is not a model by IKEA. It is just a slightly modified copy.
