Keyscrew (Pocket Screwdriver Kit v2 with rench tool)

I felt like the original design was too big and heavy for my liking, so I shortened it, added a rench hole and still kept the keychain hole.

Originally I didn't use the press-and-fit design and just left some square holes to make it shorter and try to stick them with glues, but they didn't stick well. Half of the time when I pull the cover, the “seat” was left inside. That's why I went for press-and-fit in the end, adding another 8mm to its length.

I've tried the Ratcheting End Cap version but it wasn't really strong, so I just simply left a rench hole instead. Oh, and I only had 10*3mm magnets in stock, so that was what I used.
