This is just a simple louvered accent lamp test that I designed while playing around with the idea on my way to making one that I truly like. This is offered as a free download, since I didn't really design it to hold any specific light, and didn't spend much time on it.
There is no form of light retainer, since it's only a test design. I didn't even spend the time to put in hanging holes to mount the fixture to the wall; for my test print, I heated a safety-pin and poked holes through for thumbtacks.
It has a decent sized cavity for holding some LED lights (as displayed in photo), and an opening at the bottom to accept a power cable.
I just thought I'd share it, since you never know what people might be looking for. I hope someone out there can get some use out of it.
