Magnetic Keyboard Tray

thingiverse

Makes a satisfying thunk as it clicks into place under the coffee table. More for keyboard storage than for a lap tray. The legs get super-glued to the corner trim. The magnets are then glued to the legs. I used rubber bands to hold them together while the glue dries. The pieces should friction fit to a piece of white board, or something of similar thickness which servers as the base of the tray. The metal banding under the table that it sticks to is from the hardware store, and is attached with short flat-head nails.
