My previous PTFE hose holder was a bit flimsy, and I also wanted to be able to hold a reel for ones that are too big for the dry boxes. I couldn't use the whole OEM reel holder that came with the printer because I have a shelf right above it, so this one orients the reel so that it's sideways.
Print the bracket on its side, and the hose holder upside down, and you won't need any supports. Once printed, the hose holder part slots into the bracket, and then you can twist the reel holder that with your printer into the hole to hold everything together.
