I always regret not getting the 100$ more special edition of the Massdrop red scarf III, so I thought about to add a backplate myself (the only difference was the backplate). The red scarf is my favorite MX keyboard, I use it for gaming and writing all day (Gateron red). I disliked the missing weight and support of the switchplate.
I ordered the metallplate from a shop and drilled the holes myself. The plate was not the right size, 2mm to short in length (Idk how it happened, I got the size from the manual, maybe I should measured it myself or the shop cut it wrong, but in the end it isn't a big deal).
