This cover protects the buttons and potentiometer on the Ultra PicoKeyer, a device that adds iambic keyer functionality and CW message memory to any radio. Some users have had their batteries die due to the device being put into beacon mode during transport. This prevents that from happening!
If you use PrusaSlicer 2.6 then feel free to emboss your callsign into the cover to truly make it yours!
