Decided to make myself a key holder that looks like an old JMP Marshall Head unit. All of the prints should be self explanatory. the Main body, and the handle should be the only items requiring any support material. A dab of super glue was used to join everything together. 

The Main Body, Feet, Handle, and Back Plate were all printed in black PLA.

The Gold Part, and Trim should be printed in gold 

The Logo was printed in White. 

You will need some separate hardware for the way I designed it. I used 7 Old female input jacks I had in a drawer for the amp head itself, and then 7 Jacks from broken cables. I used paracord pinched in the crimp able part of the input jack to make sure it stays put. 

The backplate should be optionable if you don't want it. I just made it for a cleaner look, a third point of contact with the wall and as an easier way to try and line up your initial screws for securing it to the wall.
