Cable Management Bar for Rosewill RSV-4000u 4u Server Case

I got a Rosewill RSV-R4000U 4u Server chassis basically for free but there was no cable management bar in the case like the photos on their website state so I designed my own. 

Has slots all down the profile of it for zip ties to do cable management. The two pegs on each end slot into the holes on each shelf lip as only the middle hole is threaded and that one has countersunk hole for a M4 w/0.7 Thread x8mm Socket head cap screw (uses a 3mm Hex bit)

Printed them face down for minimal supports.
