Assembling the RTk.GPIO Case

Assembling the RTk.GPIO Acrylic Case

The RTk.GPIO is a pin compatible Raspberry Pi GPIO header that can be connected to any USB capable computer to emulate the functions of the Raspberry Pi – Without the need for a Raspberry Pi (but can be used on one!). The project started life successfully on Kickstarter to get off the ground, and now in full production.

Check all the pieces

To assemble the case, you will find:

  • 1x Top layer
  • 1x Bottom layer
  • 1x Middle layer
  • 4x M2.5 screws
  • 4x M2.5 nuts


Peel all the backing off each layer, this is kept on after being laser cut to protect the surfaces during packing and transportation. Peeling this off can be done easily by using a finger nail and pick at the corner, and slowly peel.

Don’t use any sharp tools such as a knife or screwdriver to peel away the backing as this will result in scratches, and ruining the surface of the acrylic.

Carefully pop out any extra pieces of acrylic still stuck in any hole using a pen or pointy tool. Pay extra care with the middle layer, as some areas are very thin and brittle if handled roughly.


Place the base layer down first, with the writing showing the wrong side. This is when assembled, the writing is visible from the reverse.

Place the RTk.GPIO board on top of the base layer.

Place the middle layer on top, ensure all the components are snuggly within the cut outs so the layer fits flush with the red PCB.

Finish off with the top protective layer.

Insert a screw through the 3 layers and RPi.GPIO board to get everything neatly stacked together.

Finish off with a nut underneath to hold everything together.

NOTE: Do not over-tighten or use an electric screwdriver to tighten the screw as this will add extra pressure and result in the acrylic cracking or breaking.

Finish everything off with the remaining 3 screws and nuts.

Everything is complete and ready to use.
