btrfld v3

SolidusHal's btrfld v3 is still a foldable tenting keyboard, but now with ultra low-profile switches.

The btrfld v3, just like its predecessors, is a portable sibling of Evalyn Emmerich's aka (SolidHal/SolidusHal) original unibody btrfly. After the handwired prototype and V2 with PCB supporting Choc switches, the btrfld V3 features Cherry's MX ULP (ultra low profile) switches.

There aren't amazing sources of ULP key caps at this point. The best option I found was to print some. […] You need a reasonably high resolution SLA printer to get functional keycaps, FDM won't work – SolidHal.

Specs

• 46 keys
• Cherry MX ULP switches
