T shape background photo support kit

In need for a system to use for making photos to my 3d printed products, I designed this modular support, meaning you can adjust the height and width using extra printed parts.On the threaded segments I added extra infill for resistance, of course you can change that, depending on what material you will be using. I used only paper backgrounds. You don't have to print the bench vise's, you may use something heavy to put on the base. I will design a larger base soon, but it may have to be made off 2 parts because of the printer bed limitation. I printed it our of PLA, but maybe its more suitable PETG. Hope you enjoy and give me a boost!
