This is an Bowden tube support for Creality CR printers. I was in the middle of a long print when my bowden tube managed to wrap itself around the print and rip it off the build plate. Because of that I needed to get the tube up and off the build plate and out of the way of the print. This bracket slides into the top cross support then uses a retractable badge holder to keep tension on the tube lifting it up and out of the way. It is designed to work with a badge holder I found on Amazon. Which can be found at the link below.
I added a capture for a nut in case you want to fasten it to the cross support, but I found leaving it loose works best. When loose it can slide left and right and follow your extruder when needed. Hope this helps some of you out there. It worked well for me. I printed mine in normal resolution solid, for strength.
