I lost the camera mount of my tripod, so I designed this to replace it. Hope you find it useful for you. Make sure it will fit your tripod before printing. This mount has the bottom surface of size 38mmx38mm. The bolt is standard M6, and will fit almost any camera. Note: you will need to enable Support when slicing in order to print the bolt correctly.
Here is the Tinkercad link for you to play around with the model
