Left: CAD design of the electrospray/electrospinning nozzle capillary holder part. Right: Photograph of the white nozzle capillary holder part that has been printed from a rubber material, marketed under the name Verbatim Primalloy. The high voltage cable of the power supply was clamped on the metallic part of the nozzle with the help of a crocodile clip. The Teflon tube from the syringe pump was slid onto the nozzle that was piercing through the elastic rubber part
