+
+**For the following step, please prepare:**
+
+- 3d printed bottom housing (x1)

+
+**For the following step, please prepare:**
+
+- 3d printed bottom housing (x1)
+- M3 screw (x3)
+- M3 bearing (x3)
+
+**For each of the 3 bearings:**
+
+![](../assets/pics/guides/charybdis/56.jpg)
+
+- Install the bearing in its spot
+- Screw in the M3 torx screw
+- Make sure it can rotate freely. If not, unscrew by half a turn and check again
+
+# Spin the ball
+- If you printed the case yourself, the bearings might scratch a bit against the 3d print and not roll correctly
+- Rest the trackball on top of the 3 bearings
+- Place your palm on top of the trackball
+- Applying gentle pressure, make a circle movement, make sure you can hear the bearings rotating
+- Do this for around 30 seconds, or until the trackball feels smooth
+
+
+# Installing the 3d holder assembly
+
+## Top part
+
+- Insert the top sensor holder assembly into the case
+- The top sensor holder assembly has a specific way of being inserted
+- Locate the side with a cut part
+- Install it from the top of the keyboard, by pushing in the opposite side first. Use the picture below to check correct insertion
+

+
+Push in the other side. It will scrap a little bit against the case.

+
+## Bottom part
+
+{: .tip }
+Depending on your kit, the bottom housing might look slightly different. Install the screws to match the picture below.
+
+- Insert the bottom part of the assembly from under the case
+- Screw in the 3 screws
+- Make sure it's tight, but do not overtighten - you might damage the print
+- The whole assembly should not move at all
