Vortex Throw Levers

thingiverse

Update: I discovered that the thickened section for the screw in the V1 model interfered with my bolt handle when using low magnifications. Fortunately, the V3 design relocated this portion to the top and out of the way. The levers fit most Votrex scope adjustment rings seamlessly, while the V1 has been confirmed to work with the Viper (PST and non-PST) models as well as the Diamondback Tactical. I'm currently experimenting with two designs to create a robust scope throw lever for the Diamondback Tactical. My first attempt will be to thread the M3 fastener directly into the plastic, which should work better on the "V1" model since stresses are carried by the keys and the fastener is only there to hold it in place. The test of the V1 model was successful, although it required some effort to get the screw to form threads directly into the plastic. To achieve a comfortable fit around the screw, I had to alter its dimensions. Using a tap to form the threads would be advisable if you have one available.
