3.5mm headphone extension jack underdesk mount

Headphone extension cable jack attachment to the table. This was designed with my exact extension cable jack in mind. You might need to change some parameters to work with your extension cable jack. I've added step files. Also, if you're an onshape user, here is the onshape project link.

Note:  the pictures might look like the dimensions are wrong.  Which at the time of taking the photo was wrong. But I've since updated the model with the correct dimensions. 

Happy 3D printing. 

PS: This is my first-time 3D modeling, so some mistakes might occur. If you find one, please do let me know. Thanks!
