5x7 Dactyl Manuform

This is a fork of the Dactyl-ManuForm, with code borrowed from the Dactyl Manuform Mini. The Dactyl-Manuform is a fork of the Dactyl with the thumb cluster from ManuForm.

Features

• The use of sidenubs can be disabled. Sidenub should be disabled if you use Kailh, and Outemu. If you use Cherry MX, Gateron or Zealios switches, you can enable the sidenubs.
• Spaces for rentention tabs are added.
• One key in the thumb cluster has been removed. Other thumb keys are also adjusted.
• The total height is reduced and wire posts are removed. This results in a higher printing speed and a lower cost.
• Screw posts are moved inside. The holes are designed for TRISERT® thread inserts 145m3.
• The base plate has been modified to accommodate a custom made palm rest
• Holes for reset and power switches.
• Base plate includes nicenano holder and retention tabs. It should hold the nicenano without any need for hot glue.
• Thumb cluster has been completely reworked to include stabilizers for the 2u switches, and a layout that is more comfortable (for me).

Generate OpenSCAD and STL models

• Run lein generate or lein auto generate
• This will regenerate the things/*.scad files
• Use OpenSCAD to open a .scad file.
• Make changes to design, repeat load-file, OpenSCAD will watch for changes and rerender.
• When done, use OpenSCAD to export STL files

BOM

• Key switches
• Keycaps
• 2x nice!nano

Also not technically part of the BOM, but these Irwin wire strippers are the bomb: https://www.amazon.com/gp/product/B000OQ21CA

Build notes

• Use my ZMK config. You may need to adjust the pins used for rows/columns on the nicenano. In my config I use D5-9 for rows and A0-2, D10, D16, D14, D15 for the columns.
• This build log linked in the original Dactyl Manuform Mini repo is super helpful
• The palm rest is optional, some notes on how to make one are found in this imgur album from my first dactyl build
• To extend the base plate to accomodate a palm rest, set add-palm-rest to true in the clojure code.
• Batteries are "secured" to the base plate with command poster strips.
• Dimensions work fine on my printer, you may need to tune for your printer. See the end of the clojure code for a bunch of "unit tests" - isolated sections of the geometry that are useful to print as one-offs to test fit.
