This is the Caveman Carabiner,
at a glance it's a simple, small keychain carabiner with a stylish design and attractive lines. It's a print in place, no supports required print
looking a little closer you will see a hidden 1/4" screwdriver bit. When needed you simply remove from the bottom of the carabiner and insert into the top for use.
The driver bit is held in place by three embedded magnets that are inserted during printing at layer 54. I usually use a dab of super glue on the bottom of the magnets to hold them from trying to stick to the print nozzle.
I used some Dewalt double sided Phillips and Flathead bits. They were just $6.99 on amazon. However, you can use any types of bits you want whether it's Flathead, phillips , toque allen, whatever you use the most.

The magnets I use are also available on amazon. You get 60 of these for $7.99

Ive printed a few and found that PETG feels the best. It's strong and durable and the flex gate works the best. However, PLA does well also.
I have really enjoyed this carabiner and It gets alot of notice from friends and coworkers.
Happy Printing...
