Intro Notes: This is designed to fit Stacksmashing's USB to Game Boy Link Cable Adapter. I've designed this to be printable with the least amount of support material possible. Only the button and the switch need to be printed with brims.

The QR codes on the rear label bring you to Lorenzooone's PokemonGB_Online_Trades Github page and Stacksmashing's Online Tetris web page. Please check out these individuals projects, as its hardware and software projects like these that I love seeing/using/and making stuff for.

Print Parameters: 0.4mm Nozzle, 10% infill, 5mm(Min.) Brim on Button and Switch, 0.2mm Layer Height, 3 Vert.&Horz. Shell layers.

Additional Hardware: 4x M2 (5mm +-1mm long) countersunk screws.

Post Processing: Use a scissors and/or craft knife to remove the brim from the button and switch. The female section on the sliders and the bottom chamfer may need to be slightly shaved down, the connector shroud should slide into place tightly. On the PCB, there are panel tabs left over from manufacturing. These tabs on the left and right sides need to be trimmed off and made flush with the rest of the PCB (see pic. for example). The panel tab underneath the USB port does not need to be trimmed.

Assembly:

1. Slide the PCB into the connector shroud.
2. Place the switch into lower housing. (take note of the switch's position on the PCB and adjust the printed switch accordingly)
3. drop the USB side of the PCB into the lower case.
4. align the connector shroud's slider rails with the rails on the lower case and slide it down into position (there should be enough vertical play between the PBC and the connector shroud to do this). Check that the top of the connector shroud lines up with the top of the lower case (if it does not fit, please check Post Processing and try again).
5. At this point, hold the PCB and lower case together with your fingers and test the switch on the bottom case. Adjust the switch if necessary.
6. Take the top case and place it top down then, insert the button into the button hole.
7. Clip together the top and lower halves of the case while the pieces are upside-down (this prevents the button from falling out).
8. Place the assembly right side up, and screw together the two halves (I suppose the screws are optional as I did include clips to help secure the top and bottom together, I would recommend screwing it together though).
