Camera Plate Screw Tightener Key

Camera Plate Screw Tightener needed some camera screw keys for students to have on them when out filming quick designs and works looked online for other files but could only find ones with coins inserted inside which wasn't really something we wanted to have to do did find lots of pre made metal ones from tripod and camera manufactures for a couple of £ large quantities would have been to expensive for a college as its something that gets lost or forgotten by people all the time more and more of our students don't carry cash so cant tell them to use a coin or give them a screwdriver to take in to the streets the design in 1.85mm thick perfect to fit in a tripod screw head large body for more leverage and key ring hole
