This hangs over the top of a 1" cubicle wall and holds a set of headphones. The headphones pictured are 1" wide at the top of the band and fit with plenty of room to spare.
Prints in 2 pieces and assembles with an interference fit. For peace of mind I recommend a dab of CA out of sight and this hanger will not come apart!
I printed the arc of the headphone holder standing on end and it came out great, no supports needed here. Happy printing.
