Let’s take a closer look at the image for a moment.

As far as this is concerned, it appears to correspond to three mounting methods.
However, it may be necessary to order a case for each mount, as the construction of the case itself appears to be different.
Difference in mounting structure by case
- Integrated mount: A structure in which the plate is part of the case. The plate is formed together with the frame when the case is formed.
- tadpole mount: A mounting method using silicone poles sold by GEONWORKS. It is highly flexible during keystrokes.
- TOP mount: Plate is fixed with screws.
Commenting on the addition of this case-mounting method, he said
When we were developing the cocot38mini v1, the underlying theme was less packaging = less BOM, so we started with a screw/spacer-less integrated mount + snap-fit case. With this update, we’ve added a top mount and a tadpole mount, both of which are more focused on the key feel.
