Parametric Keyboard

Decided to hand-wire my own macro-pad and ended up creating a parametric design in Fusion 360. You can change the number of keys on the X- and Y-axes using the parameter function in Fusion 360. You can find the Parameters under the ‘modify’ tab. A 4x5 layout is used in the stl file. The case and plate screw together using M3x16 bolts, no standoffs necessary. There is no reason to use all the available holes to mount the plate, it was just necessary for the parameters to work properly. The height between the bottom of the case and the plate is 10mm as default. You can increase it using the ‘KHE’ parameter but I haven't properly tested whether or not adjusting the height breaks the model. The plate only fits MX style switches, I built mine using Gateron Low Profile Reds and Browns, I also tried Logitech switches, Outemu switches and Cherry switches with success. The micro-controller used is an Arduino Pro Micro (ATmega32u4). The generated plate is the same size you get when creating
