Janky Variable Power Jupply

~This is my first post on thingiverse (or other such sites for that matter) so plase have patience as I'm figuring this thing out.~

12V Variable power supply case ( electrical design coming soon - but it's simple really).
Fully parametric.
Fusion 360 file - full file.

Finished product pictures coming up ( still printing)

Will return with pictures and schematics.

Simple electrical build, simple components:

1. 220VAC - 12VDC 3A power supply, model S-36-12 - Full Chinesium

2. Simple LM317T Voltage regulator build using:
- 1X 2X8cm perf board
- LM317T Voltage Regulator
-1X100nF ceramic Capacitor between imput and ground
-1X10uF electrolitic capacitor between output and ground
- ~500Ohm resistor (or equivalent) between output and Adj pin
- 1X 10KOhm linear pot between Adj pin and ground for adjusting output voltage.
- 1X heatsink for the LM317T - the bigger you can fit in the better .

3. 4X metric 4 female banana plug (make it 2 red 2 black for fancyness, bu
