Just some organization accessories I made for my desk at work.  It's a SwiftSpace desk with the accessory rail listed here:  

Small shelf, a peg type hook, a small clip that holds a sheet of paper or an index card, and a headphone hook for my LG Tone headset.  

The peg is two parts because I didn't want to use support to print it.  It's a tight fit and able to support a large roll of masking tape as it was, but I used some Maximum Bond Krazy Glue (my new favorite 3D printing tool) to secure the parts just to be safe.

If I come up with more accessories, I'll try to post them here.
