Features
3d printed case, with a top and bottom section. Two EC11 rotary encoders. 6 Keys.
CAD Model
Everything fits together using 4 M3 Bolts and heatset inserts. 4 for the case.
It is made of 2 separate 3d printable pieces.
Made in Fusion 360.

Firmware Overview
This hackpad uses KMK firmware for everything. The left rotary encoder zooms in and out. The right one increases and decreases volume. Press any to mute. All the other keys are function keys (F13-F18) so I can easily reassign them to another tool later. To install, upload the KMK firmware package, and then add the main.py file.

Questions
How big is the Zenithpad PCB?
It measures 57.2 × 57.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Zenithpad use?
9 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Zenithpad KiCad files?
From the HIIACODER/zenithpad repository on GitHub, at the commit this page was made from: the board is PCB/zenithpad.kicad_pcb and its schematic PCB/zenithpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Zenithpad design in my own project?
Its repository states no licence, so its author keeps all rights: ask HIIACODER before reusing the design.
