Quefrency Ergonomic Bases w/ Palm Rest

thingiverse

This base set is designed specifically for the Keebio 60%/65% mechanical keyboard kit: https://keeb.io/products/quefrency-60-65-split-staggered-keyboard?variant=16032980861022. A recent update was made on July 10, 2020, which included adding one-piece bases. This allows users to print the bases in a single piece if their print bed is large enough, rather than bolting them together. Printing the bases in one piece is the preferred method for those who can accommodate it. There are two palm rest sets available: the normal set and the 'tall' set, which is 5mm taller. The black palm rests shown in the pictures above are the 'tall' rests. I prefer the lower set as it allows my arm to contact the desk more easily, rather than putting pressure on my wrist. I wrapped my palm rests with 3M Carbon Fiber vinyl wrap, which I purchased for $7 or so from eBay for an 8in x 11in sheet shipped.

I used the official Keebio middle layer files found here for the location of the boards and designed the rest in Fusion360. The angles used in this design are loosely based on the Microsoft Ergonomic 4000 keyboard, which I used for about ten years before switching to a mechanical keyboard. The features include: * A 6º tent angle * A 3º forward tilt on the keyboard and palm rest * A 35mm plate height in the middle back with an 11mm offset in the right front corner of the right plate, which is 2mm lower than Keebio's middle plates * Palm rests that are 100mm deep * Bases cut into four pieces to accommodate smaller print areas (191mm is the longest length) * All base pieces can be printed without support * Palm rests should be printed upside down on the sloped surface with build surface supports only The required screws include: * (12) M4 x 10mm screws for mounting tall palm rests * (10) M4 x 10 and (2) M4 x 6mm screws for normal palm rests * (4) M4 x 14mm screws w/ washer and nut to bolt base pieces together * Keyplates mount with M2 screws that self-tap into holes, and the screws that come with the Quefrency 65 plates work fine There are also recessed rubber foot areas (12mm x 2mm) that can be used if you want to add small rubber feet without raising your keyboard much. Other build points include: * Applying thin strips of electric tape on surfaces that keyplates/palm rests will contact and tightening screws until snug only * Cutting squares of neoprene mouse pad and mounting two layers in each base opening with spray adhesive, which helps minimize noise * Using rubber feet on the bottom to keep the keyboard stable and put pressure on large open areas * Applying a strip of electric or fabric tape on the base faces you bolt together to ensure there's no vibration sound * Sanding palm rests for a smoother surface and considering covering them with faux carbon fiber car wrap or wood pieces like dark walnut * Swapping out M2 screws that came with plates for M2 x 8mm hex bolts for a better look
