This is a mount that holds the bottom of a venetian blind from moving - if your blinds can use it. My house is fairly old, and on my back door there's a venetian blind that's mounted on the inside of the door. The brackets that hold it down are what the blind came with, and about a year ago one broke and it was old enough that I couldn't find one, or never really looked when I was at home depot.So then I remembered one day while letting the dogs out, and I went and retrieved the one good mount I had, and I built it up in Sketchup and printed a replacement.When I first started printing this, I hadn't yet done PLA with a fan, however, we were having a December cold snap (I'm in Colorado) and I took my little floor heater and put it up on the table, having read that it can help.This latest revision is a complete perfect copy of the original, however, to get all the details you'll have to print it in PLA, hot, and use a fan.In my setup, I ran this PLA at 225C and sliced it using Slic3r at .25 per slice. A fan is mandatory to get the top details on this.
