Green Screen PVC Frame Clip

thingiverse

I have a large DIY green screen behind my desk for videos and livestreaming that's constructed from 3/4 inch schedule 80 PVC pipe. The base prevents it from falling over easily, but it also has a bar along the top for mounting clamp lights, which makes it tend to lean away from the wall due to their weight and the screen itself. The DIY fix I designed holds the screen vertical by snapping one or more clips around the light mounting bar or the vertical pipes on the sides of the screen. Then they're nailed or screwed directly into the wall to keep the screen upright, just like a strap that comes with flat-packed bookshelves. To add extra stability, you can use the small nubs on the round clip as attachment points for optional retainers like bread ties or elastic bands. A note: since my green screen is long enough to partially cover a nearby window, there's always going to be a gap between the frame and the wall. To address this, I might add a spacer in the future, but if you need one now, simply flip the clip upside down in your slicer with curved bits facing down, scale it on Z so the desired height is achieved, then cut off the curved bits. In Cura, use the Cut Off Object Bottom field on the Advanced tab to do this.
