The btrfld

u/SolidusHal's btrfld is a quite unique foldable, low profile, tenting keyboard.
Published April 27, 2022

Pronounced "butter-fold", btrfld is the foldable, portable sibling of SolidusHal's btrfly keyboard introduced almost exactly a year ago.

This is a handwired prototype but the STLs are published.

Folding mechanism

The keyboard features a carefully crafted and pretty unique folding mechanism for better portability:
