Macro Knob and Keyboard

grabcad

This is a remake of vmensik's VM's macro keyboard over at prusaprinters.org. (https://www.prusaprinters.org/prints/30745-vms-macro-keyboard) I didn't really like the rugged look on top, so the model was completely reworked to remove the ridge around the knob so that it can be printed upside down without supports. The key holder tray was also removed in favor of mounting the keys directly into the case. A cable strain relief, a place for a micro usb port, and a slide switch were added for more connectivity options. The slide switch was added to enable switching between macro profiles. All of the source files are uploaded so feel free to add/remove these features or to change screw hole sizes and tolerances. Note: if using the usb port it must be mounted upside down as shown in image.
