This is my take on an infinity style photo backdrop stand. It has built in clips to hold the paper. I added springs to enhance the grip on the paper.
No support needed.
This is not a "remix" technically as I designed mine from scratch but it was absolutely inspired by the "Photographic Sweep Stand" by HPaul.
Also, I used a great chip clip design by srwilson58 and modified it for my purposes here.
I added "no spring" versions which just have the spring clip separated. You NEED to print the spring clip file ONLY if you print the "no spring" versions of the stand sides.
Just install the spring in to the bottom of the clip as shown in the pictures. If assembled correctly, the spring will align close to the upright. If it's installed backwards, it will stick out but still function just fine.
