At a customer's request, I created this stand specifically to hold split keyboards. It's compact, sturdy, and features a stepped surface to help account for the thumb cluster that protrudes on most split keyboard designs such as the Iris, Corne, and Sofle. The stand is 3D printed in black PLA plastic and comes with four rubber feet attached, so it won't slide around on your desk or shelf. The bottom of each keyboard slot is lined with a strip of soft EPA foam, so your boards won't slide around either.
The unit measures 5.5" x 5.5" x 2.5". (140x140x65mm)
