These are cheap stands that do a great job holding up your keyboard and staying out of the way.
I particularly like these for displaying extra builds (PCB + keycaps).
I would not recommend these for overly heavy boards or for most Alice clones (especially if they are slightly pointed in the middle).

This is one of the more interesting finds I have come across recently. Anyone who has stocks of keycaps waiting for a home can find one for about $10.
