I created a simple, custom-sized remote control holder for:

• Aeotec Z-Wave Minimote
• Roku 3 Remote
• Xfinity Remote
• Vizio TV Remote
• Wiimote Controller

Each slot is sized to fit each particular remote. I also added text labels to each (for fun).

Although it works well, I ended up using the wrong measurement for the Xfinity remote, making its slot (and the entire holder) wider than I'd like. It still works just fine though!
