I designed this 3D printed cable holder to attach to the top of an Intellijel 7U 104HP performance case when it is upright (photos illustrate a case attached to another case via the Intellijel joiner plates). It hooks to the front lip of the case for stability.
If you would like this in a different color, please check out my other listings on Etsy (NightOwlModular) or send me a message.
