10 X scale models of adjustable - dose malaria drug delivery ‘pens.’ Acrylic tubes formed the models’ main body. The caps were vacuum formed in polystyrene, as were the lower bodies. The lower bodies were formed in halves and slots were cut into them. The raised ribs were made from polystyrene rod, planed flat on one side, heat softened, and solvent welded to the body. The threaded tips were turned on our lathe. The raised Schering-Plough logos were cut from thin polystyrene and solvent welded on. Beaded styrofoam inside a clear window behind the slot simulated the drug in its glass ampule. The bodies, and different color caps, were all painted with automotive lacquer. All the lettering on the models was done via applied transfers.
