Pretty self-explanatory. Cover that "step" key with a 3d printed cover. See https://www.thingiverse.com/thing:4584044 for free download. No PathPilot script editing, etc.
Files include 3 different covers. "Cut cover" has a notch to allow a discrete finger press of the step button if you'd like. Tall is a bit too tall but may add safety for heavy hands.
This fit's very tightly, scale up if you'd like a looser fit. Notch is for shuttle power cord. Printing tips on thingiverse site.
Feedback appreciated.
