Elfa Shelf Bracket Headphone Hanger

I've got some Elfa shelves hung above my desk in the office. I get a lot of use out of them including using them to hang various items underneath.

So after knocking my other hanger from the edge of the desk for the Nth+1 time, I decided this needed to move above and out-of-the-way.

The way the Elfa wire shelves are designed they have these U-shaped brackets which are open at the top. So I designed this hanger to slip between the wires and then down into the bracket cavity. It uses the bracket itself to support the back and feels very sturdy.

I tried to strike a balance between minimizing material use and print time with strength so a chamfer here, and a chamfer there. But in the end it's only having to support a pair of headphones.

Print instructions

I intended this to be printed laying on its side to make sure the layer strength was in the proper orientation.

I felt this necessitated the use of supports on the build plate to make sure the curved portion printed well. I used the .2mm offset to make sure it was easily removed. You might be able to get away without using this, but it exceeds the 45 degree angle guideline so your mileage may vary.

Other than that my attached 3MF file details my settings. My print file is sliced for PETG.

I must say that when printed in clear with the gyroid infill you get some really cool visible infill patterns.
