An Apex Legends Gas Grenade from Caustic. It has a lock system to lock the Grenade when its open. You can add magnets for an better feeling. I used 5x1 mm magnets. The magnets are Not necessary. You need 4 M3 Screws and nuts. I upload the step file if you want to change something. If there are any questions ask me in the comments.
For the Top part you need to insert 3 M3 nuts. Make a filament change and insert the nuts, load the same filament and print further on.
All common Materials can be used.
Insert the grid insert into the top part. Screw the top_part 2 onto the Top_part 1 with 3 M3 Hex screws. Then Glue in the Magnets (if desired) in the Top_part2 and the base. Glue the base and the Grid insert together.
