Ender 3 Tool Holder add on for power supply

This remix is a result of comments and suggestions received after posting the first the first powers Supply Tool Holder:
1--More storage space for small and large SD's
2--place for cutters on the front
3--more support in the rear to contact power supply

I added the additional supports (1mm) each side and included it as .stl (rev2). The additional storage and mount for the side cutter is simply a new piece that fits into the existing tool holder. Hope others find this useful!
