Plateless
Kit
Inspired by Geon's F1-8X plateless kit, I wanted to make a plateless kit for existing keyboards... so here we have
SIMP KIT
The idea is to sandwich the pcb in bottom of the case using 3d printed pieces.
These were printed out of TPU.
Advantages of Plateless:
- Soft flexy typing experience
- Can easily access switches for modification
- Can pop stab wires back in easily
Advantages of SIMP:
- Flexibility of mounting positions allows for customization of typing feel.
- Using different hardness plastic can also change typing feel
- Can easily retrofit for boards that have a bottom "tub"
- Does not require specific board/pcb design to work
- Cheap

How to design:

If the bottom of your case has a tub, i.e. the PCB can rest in the bottom of the case, you can SIMP kit it (probably).
You will need to measure the "gap" and the "depth".
The gap is the distance between the PCB edge and the inside edge of the case. Shown here:

The depth is the distance from the bottom of the PCB to the bottom of the case. Shown here:

This is an annotated image of the SIMP kit insert with the relevant measurements by Nevin.

I've found that the distance from the PCB to the top of the case does not matter much since there often isn't a ledge to hold the piece in.

Special thanks to my friends mxblue and suyash for helping me refine the idea.
