The glassware or test tubes are placed on triangular pegs, which allow the water to drip onto the tray and then through a tube to the sink. The rack can be attached to the wall over a sink or mounted on feet. The 10 mm x 8 mm flexible tube costs less than $6 on Amazon. A dab of grease on the tube end prevents leaking between the tube and tray.
A similar unit is available from McMaster Carr for $411.
I was too cheap to buy test tubes for the photograph, so printed a large one and small one In PLA.
