Hi,

lately I completed a mechanical retrofit to a CHERRY G81 1800 HQU rubberdome keyboard.
This keyboard has nice double shot keycaps and I found a new and very cheap one on a local listing.
The retrofit involved replacing the pcb with a G80 1800 Leeche (cina) one and adding a self designed/modified stainless steel plate to add rigidity to the whole assembly.

I believe I started from this plate design and modified it to my needs:

I published a video of the whole process and I've been asked to share the plate design so here are pictures , video and download link for the plate design. If You're going to use my design, please always double check everything before you start ordering parts.
