## Step X: Remove support material from 3D-printed parts

**TODO photo of top with support material**
|

|

The top has support material that must be removed prior to use.
|
||||
|
||||
"Support material" is more hollow than the structural plastic. You'll have to remove it before you continue with the assembly.
|
||||
|
||||
Most of the time, it can be removed using nothing but your fingers. If you find a bit of support material is sticking, use a pair of pliers or tweezers to scrape it off. Be careful not to damage the parts as you remove the support material.

## Step X: Solder ADNS-5050 sensor to printed circuit board
|

|
||||
**TODO create video of ADNS-5050 being soldered**
|
||||
Before soldering:
|
||||
- **MAKE SURE THAT THE ADNS-5050 IS ORIENTED CORRECTLY BEFORE YOU SOLDER IT!** This is a really easy step to mess up, so *DOUBLE-CHECK IT!*
|
||||
- The sensor must be flat down as far as it can possibly slide into the holes before soldering. Don't let it "float" while you're soldering the first pin down.

- Try your best to copy the placement of the tape as is shown in the photo.
|
||||
- When the tape is installed, it should align with the hole in the PCB (which is inserted in the next step).

## Step X: Place printed circuit board into base
|

|
||||
**TODO photo of PCB in base**
|
||||
|
||||
|
||||
- Make sure that the printed circuit board is oriented correctly. Most of the electronics will be hidden when the board is inserted correctly.
|
||||
- The printed circuit board might require a tiny bit of force to push in.
|
||||
|
||||
## Step X: Place ADNS-5050 sensor optic into top
|

|
||||
**TODO photo of sensor optic placed down**

||||
TODO: top cavity must be flush
|
||||
|
||||
|
||||
- It's done this way to make installation easier. Just trust us on this one.
|
||||
- Make sure that there is no support material left in the cavity of the top. The optic must sit completely flush with the cavity, or the top and bottom won't fit together correctly.
|
||||
- Make sure that the optic is oriented correctly. If it's not oriented correctly, the optic will bump into the sensor in the next step.

|
||||
|
||||
- Hold the top upside-down, and place the bottom onto the top. The printed circuit board shouldn't slide out.
|
||||
- Only a tiny bit of force is necessary to put the two pieces together. If you have to press hard, something is very wrong. Take it apart and repeat the above steps, making sure things are oriented correctly.

- Ensure that the bearings are pressed all the way into the case. If the bearings aren't seated all the way, there's a good chance that the ball will become badly scratched.

||||
- Needle nose pliers or some similar tool can be used to ensure that the bearing is fully seated.

- If the ball is too shiny, the sensor isn't going to pick up a lot of the detail on the ball

- Therefore, in order to make the Ploopy Nano function better, you'll have to remove a bit of the shine on the ball
