Walther PPQ 22lr Rear Sight

thingiverse

The rear sight on my PPQ 22lr broke within days of getting it. The stock sight is cheap cast aluminum with a dovetail that does not extend the whole way across the slot. On top of that, my firearm shot high. This is a fixed rear sight that address the durability issues and well as the accuracy of the sight picture. There are 5 different height sights. I ended up using the 5.2 rear sight with the #4 front sight that was stock. You may need a different combination for your firearm. The sight is held on using a #4-40 hex nut pressed into the bottom of the sight and a #4-40 set screw (1/8" long set screw is long enough). Print with the hex nut hole against build plate (rotate stl file 90 degrees) in super high resolution with supports from build plate. I used tree supports (under experimental in Cura) and they came off very easily.
