Easy SKADIS hooks to add to custom boxes

I really liked the design of the back of the hook that goes directly into the pegboard itself. It has a nice width that allows it to be easily added and removed from the pegboard, but also provides enough strength to hold pens in a basket once the hook tines are elongated a bit. I remixed this model for 2 reasons: I wanted the tines to be longer so that the hook is a little harder to remove from the pegboard, but I also wanted a hook design that's easily added to my own custom box designs. 

To help me maintain the proper vertical spacing of the 2 small hooks, I intentionally left a 1D rectangle between them that doesn't print. Once I added a vertical line halfway through the hook model in my 3D modeling software and figured out the dimensions of the SKADIS pegboard, it ends up being really easy to properly space multiple hooks on a custom box!  The vertical line doesn't show up in the STL file of course, but it's highlighted yellow in an example picture. 

Helpful tips:

I figured out the SKADIS pegboard dimensions by referring to this model https://www.printables.com/model/153436-ikea-skadis and I added a comment that includes the pegboard measurements.

I have successfully printed a box that included 2 of these hooks that I printed with PLA and 15% infill, picture of 3D model attached
