Its a hook! On a clamp! For your headphones! (Or whatever you want)
The green rings in the photos are 14mm x 2mm rubber washers. There are recessed grooves to glue them down. They help with table grip.
This is my first public design from scratch. It seems to work fairly well.
Also my first time making custom threads in Fusion 360.
You'll want to print the bolt with the large side down (i'll upload a fixed orientation later). Holder stl orientation is where I printed it.
0.2mm layers should be fine, but I did 0.1 to help with the feel of the threads.
I did 4 perimeters for strength.
Use a brim!
