Marshall jack keyholder

I took inspiration from other keyholders made with jacks (or RJ45 ethernet connectors) and I decided to design this Marshall amplifier version for a friend of mine.

This project is not a simple print-and-assemble one, I had to use different materials and tools. Here you have the lists

In the .zip file you can find the entire 3D model in SW2020

Materials:
- Aluminum bar 2x 120x30x2 mm
- A piece of women sock (black)
- 4 female 3.5mm audio jack (stereo or mono is the same)
- 1 to N male 3.5mm jack to create your keychains (in the pictures you can see that I made an aluminum custom jack with the lathe just for fun)
- black, white and gold spray paint
- 4 wood screws 3.5x15 mm (or similar)

- various diameter for the other holes

- Countersink
