This is a quick tool I designed which makes it much easier to disassemble and reassemble the bolt of a CZ 455. I have not tested it with a 452 but it will likely work since the design is the same. It will *not* help you with a 457, but the good news is that the new bolt design is way easier to work with.

Native cad in solidworks is included, so feel free to modify.

I usually just print this part solid.

This was imported from my old Thingiverse, where someone left a comment that still makes me smile to read.

Thank you for taking the time to make this design. I just finished printing! Came out perfect! It was my 3rd print after getting my first ever printer set up. It was also at the point I needed to change from the white PLA that came with my printer to the green spool I bought so it has this awesome colour change going on! Just tried it out and it makes a frustrating and frankly dangerous and potentially painful task an absolute breeze. Thank you again!
