+**TODO PIX completed enclosure; underside and topside showing shit inside**
+
+## Step 1: Get the necessary tools
+**TODO PIX**
+- A soldering iron
+- 2.5mm Allen key or screwdriver
+
+## Step 2: 3D-printed parts
+**TODO PIX**
+- Base
+- Primary buttons
+- Secondary buttons
+- Scroll wheel
+- Scroll wheel holder
+- Scroll wheel holder holder (holder holder holder holder...)
+- 3x roller bearing dowels
+- Top
+
+**If you don't have these 3D-printed parts, see `Appendix B: 3D-Printed Parts` for information on how to get them.**
+
+## Step 3: Hardware
+**TODO PIX**
+- 6x M3 screws **TODO is this right??**
+- 6x heat-set threaded inserts
+- 3x roller bearings
+- 2x metal dowels
+- 1x silicone ring
+
+**If you don't have the hardware, see `Appendix D: Hardware` for information on how to get them.**
+
+## Step 4: Preparing the scroll wheel holder
+**TODO PIX**
+- Electronics assembly
+- Scroll wheel holder
+- Scroll wheel holder holder
+
+## Step 5: Insert scroll wheel holder holder into electronics assembly
+**TODO PIX**
+- **Ensure that the plastic part is oriented correctly**
+- The plastic part requires a bit of force to get into the PCB; be careful not to damage the electronics assembly
+- Press the plastic part on its edges, NOT the middle, as you may break the part if you depress the middle too hard
+
+## Step 6: Insert scroll wheel holder into scroll wheel holder holder
+**TODO PIX**
+Stop laughing at the names already.
+
+## Step 7: Preparing the base
+**TODO PIX**
+- Base
+- 2x heat-set threaded inserts
+
+## Step 8: Put threaded inserts into base
+**TODO PIX**
+Take your time and go slowly. A soldering iron temperature of 350C or 620F is hot enough.
+
+## Step 9: Assembling the base
+**TODO PIX**
+- Electronics assembly
+- Base
+- Primary buttons
+- Secondary buttons
+- 2x M3 screws **TODO is this right??**
+
+## Step 10: Place electronics assembly onto base
+**TODO PIX**
+The electronics assembly is seated on the base, but it does not attach. It will eventually be pressed down by the Top, so don't worry about that here.
+
+## Step 11: Screw secondary buttons into base
+**TODO PIX**
+**TODO which screw here?**
+
+## Step 12: Screw primary buttons into base
+**TODO PIX**
+**TODO which screw here?**
+
+## Step 13: Preparing the top
+**TODO PIX**
+- Top
+- 4x heat-set threaded inserts
+- 3x roller bearing dowels
+- 3x roller bearings
+
+## Step 14: Put threaded inserts into top
+**TODO PIX**
+Take your time and go slowly. A soldering iron temperature of 350C or 620F is hot enough.
+
+## Step 15: Put roller bearings onto roller bearing dowels
+**TODO PIX**
+
+## Step 16: Insert roller bearings into top
+**TODO PIX**
+
+## Step 17: All done!
+**TODO PIX completed enclosure halves**
+Congrats, you finished assembling the enclosure! Pat yourself on the back.
+
+When you're ready, proceed to `4. Final assembly` to continue.
