Description
When using red dots, the proper way to aim is with both eyes open. This cover will force you to do that by blocking view through the window. When aiming with both eyes, you should simply see everything and you don't notice anything blocking.
This should fit the red dot so tightly it should withstand shooting. We did test this shooting on Walther PDP steel frame but because recoil is different on different firearms, the mileage may vary.
When used, model will be experiencing stress forces, cracks may develop over time. Maybe nylon based filament would be better, TPU potentially, we did not test this (yet).
If you feel like supporting more please use https://ko-fi.com/koudy . Please only do this when you are absolutely sure and can spare the money. The model is free for personal use and ko-fi is only way of showing support if you'd like to do so.
Print it upside up with supports. Supports should be below main top, below backside and below cutout for buttons.
