# LAB Case Build Guide
It's time to enclose your ODS board, screen, and encoder in an rugged case that includes a mount for your reader and more.
## Tools Needed
* Wire Cutters
* Soldering Iron + Solder
* 2.5mm Allen Key
* Industrial Superglue
## Parts Needed
Either from the official kit or self-manufactured.
Using parts from the kit or self ordered, and built following the [previous build guide](/opendoorsim/build-guides/screen-and-encoder).
The kit comes with all parts needed for the following steps.
If you want to double check you have the parts, or don't have a kit, or are self-ordering, check out the Lab Case's [Bill of Materials](/bill-of-materials-lab).
# Build Guide
**Official kits come with the decal tile already assembled.**
Avoid snapping magnets together as they may break from impact.
Insert 1x thin magnet (20x10x3) into the decal tile.
**North** side should face in and towards the logo.
Once inserted, only the **south** face of the magnet should be visible.
Insert 1x thin magnet (20x10x3) into the case body for the decal tile mount.
**North** side of the magnet should face out and away from the case. This magnet serves to snap the decal tile to the case.
Once inserted, the decal tile should snap to the case!
Insert 4x thick magnets (20x10x3) into the case body for the module mounts.
**North** faces should go out and away from the case.
Insert 4x thin magnets (20x10x3) into the end caps.
Only the **south** side of the magnet should be visible after insertion.
After insertion, test that the end caps snap to the case!
If magnets do not stay seated in the end caps, use some industrial superglue.
Lay down a very thin line of industrial superglue in the ring circle on the case lid.
Remove backing from magnetic ring, align, and install.
Plastic gives off harmful fumes when heated or burned. Work in a well ventilated area and avoid direct inhalation.
Align 13x threaded inserts over the insert holes. The small end of the insert should set nicely in the insert hole.
Once inserts are aligned, heat press with a soldering iron or threaded insert press. **Inserts should end up flush or slightly under the body line**.
Mount the OLED screen using 2x short screws (M3x4) on the **outermost mounting holes, leaving the innermost mounting holes clear** to allow for other components.
Mounting the OLED using the two innermost holes will make it so your other components do not sit flush. If you wish to use those threads, obtaining a flatter or lower profile screw would allow for sufficient clearance. We have found mounting the screen with the outermost holes to be sufficient.
Mount the encoder using 2x long screws (M3x6).
Once mounted, slide the knob on the encoder post from the other side.
You may want to jump forward one step and connect your reader to the ODS board before fully mounting.
Carefully slide the OpenDoorSim Board into position, pressing down and aligning the USB-C port with the case hole before pressing down and sliding the board into place.
Mount ODS Board using 3x long screws (M3x6)
Now is a great time to mount your reader of choice to the universal mounting plate, and connect your reader wires to the OpenDoorSim board.
For more details, see [Connecting a Reader](/untitled-page).
Plug respective JST connectors from each component into their JST socket on the ODS Board.
Trim the ends of the 4x module pogo wires.
Align the pogo wire with the mounting hole.
Gently press the 4x module pogo wires into their mounting holes in the case lid.
Be careful not to press directly on the magnets of the pogo wires or you may push them out.
Position the pogo wires as in the image below.
Failing to position the wires as seen below may result in the case not closing!
If desired, route the pogo wires to "X" and spare power screw terminals on the ODS board (X1, X2, X3, X4, X5, X6, etc). These are currently open in the hardware / software design for future module implementation.
There are no official modules (yet), and as such, there is no official wiring for module data and power pogo wires. Wire and implement at your own risk!
Align triangles on the case body and lid and close gently but firmly. Although it is a tight fit, you should NOT have to force the case closed.
DO NOT FORCE CASE CLOSED. If the case is not closing, there is an alignment issue, or components that are blocking closure or blocking each other. Go back to previous steps, and look inside the case to find the issue and adjust. Once adjusted, the case should close.
Screw the case closed with the allen key (2.5mm) and the 4x long screws (M3x6).
Slide the allen key into the storage slot when finished.
Snap on the decal tile, and end caps... and you're done!
