Universal tumbler holder

I made this tumbler holder because I wanted something that could hold tumblers of different sizes and could easily be attached to anywhere with a carabiner. You'll need a 3d printer to print the models out, some rubber bands (although they can be optional) and some paracord or bungee cord. Once you put together the 3d model, then you'll want to tie your tumbler to the holder by feeding it through the various slots in the rails. Once you've tied your tumbler to your holder, then you can use a carabiner at the top to easily attach your tumbler to any bag or belt. Print it out and try it out to let me know how it works for you.
I'll make a video to go over the setup of this holder and post it here. There's a certain way you'll want to print out some of the parts (like the pivot and the grips you attach to the pivot). Definitely go over the pdf document if this model doesn't seem straight forward to put together. Don't print out the parts that are supposed to flex at a high infill because then they may not flex and work (read the document). If something is not clear, please let me know and I'll get back to you as soon as I can.
I said I'd upload a video reviewing this print and model. Here's the video. Also sorry I forgot to upload the thread model before. I'll also be uploading the blender file that has the 3d models in case you want to edit them in Blender and make something yourself.
