1) Remove the f'iz:ik name plate and unscrew the stop. 2) Insert the mount and reattach the stop. 3) Mount the desired arm and go.
This mount is our newest and strongest f'iz:ik universal mount; however, it is not compatible with the 3 mm Shapeways arm.
For fi'zi:k saddles, a 3 mm and 4 mm version is offered. The 3 mm version is intended only for customers who purchased our previous DIY mounts or arms on Shapeways.
In the left picture, the 3mm f'iz:ik mount on the left is compatible with the original Shapeways DIY arms. In the image in the middle, you can see that the arm attachment screw is smaller. On the right picture you can see that the mount and arms are thicker on the new model.
