I printed a replacement part for the hard drive cover on my Lenovo Thinkpad X200. I still love this machine even though it's more than 15 years old. It's perfect for hacking software and hardware.
Luckily, somebody already created a model and shared it on Thingiverse, here. As already reported in the comments there, the inner part of the hole for the screw is free floating, which inevitably created some issues, but I just removed some of the loose strings of plastic and the rest was still enough to give enough support. For my first print it is definitely good enough. The staff was very friendly and helpful.
