Móc Khóa Lưu Trữ Muzzle Brake (30cal)

I found another key chain storage tool for rifle thread protectors on Makerworld and it gave me the idea to make one for muzzle brakes, as I also use a muzzle brake as my thread protector. So here is my design. It is made for a 30cal Muzzle brake but should work fine for a 5.56/.22 muzzle brake if you size the main shaft down to 5.4mm diameter. Size down the nut accordingly as well

This is meant to store your muzzle brake while using a suppressor, and make it easier to find later.

The nut is a printed 6mm nut, the threaded shank is 20mm long. 

I set the infill at 100% and did 10 walls for longevity.
