Fallen AT-AT Airbrush holder

Hello all. This is my first attempt at doing something sort of on my own. I wanted to find a cool way to hold my new posh airbrush lol. i saw someone selling something like this design on eBay. I tried to look for it so i could print it (why do you wanna pay someone to print it when you have a printer right?!?!) but found nothing. So i found 2 files i thought might work and merged them. Made it look good and functional, changed dimensions and such but that's it. Never done anything like this before at all. I genuinely hope I've done this all correct. Please, if I'm wrong be kind and let me know. Thank you and i hope someone at least likes it… I am printing right now and will add finished photos asap
