I upgraded a bunch of the dimmer switches in my house to the Lutron Caseta wireless remote switches, and I wanted a holder for all the remotes so I could control the lights from the laziness of my couch :-) I am not impressed with the wireless bridge module that would allow me to control the lights from my phone - not to mention the lack of privacy of another company having my peonal info. Anyway, I designed this to hold six remotes, and it works great! It uses these #4-40 stainless steel Torx flat head screws from McMaster-Carr. I printed it in a matte black filament that makes it look so much better than the shiny filaments.
