I made this 3D printable ThinkPad UltraBay Cup Holder for my T430, however it’s going to fit any similar ThinkPad UltraBay. 

The model seen in the pictures may differ, I made this published version simpler to make it simpler for all to use, as it turns out the TPU insert wasn’t necessary and the leather lace doesn’t do much.

Thanks to r/thinkpad for being such a fan of my creation that many wanted to print it
