There are two versions of this model: One for 2020 extrusions mounted with M4 screws, the other mounted undeneath a desk with M2 wood screws. both are oriented for printing and should print well with anything from 0.3mm to 0.6mm.

The 2020 version is designed to mount with low profile screws, but you can use standard M4 button heads if you want.

The hooks are great for organizing your USB cables, or in my case: storing my guitar cables away when not in use.

I've provided the Fusion files for easy modifications or you can suggest an improvement/customization in the comments.
