I don’t know if it comes across well… @nori_keyboard designed this “bottom block”, or let’s call it a “bottom block”, which is a structure where you remove the bottom plate, fit the acrylic switch plate from the top, and screw it on from the bottom. It has the transparency and weight of machined acrylic.

This is the case where Gravity36 is transformed into a single block. https://t.co/P8jqcHLnUX pic.twitter.com/XhadzbyBEp
My Gravity36

The name “Gravity” reminds me of “Space”, and from there I create cases with the image of a “monolith”. #Gravity36 #homemade keyboard pic.twitter.com/bykM5Pvi9U
Currently, a pre-soldered “Limited Edition” with a limited edition acrylic included is also available.
