Marshall jack keyholder

thingiverse

I drew inspiration from other keyholders crafted using jacks or RJ45 ethernet connectors and designed this Marshall amplifier version for a friend of mine. This project was not a simple print-and-assemble job; I had to use different materials and tools. Here are the lists you asked for: In the .zip file, you'll find the entire 3D model in SW2020 format. Materials: - Aluminum bar: two pieces, each measuring 120x30x2 mm - A piece of women's black sock - Four female 3.5mm audio jacks (stereo or mono, it doesn't matter) - One to N male 3.5mm jack for creating your keychains - Black, white, and gold spray paint - Four wood screws measuring 3.5x15 mm (or similar) - Superglue Tools: - Drill - Drillbits of various sizes (depending on the female jack size, I used 9mm in my case) - Various diameter drillbits for other holes - File - Countersink Unfortunately, I don't have pictures of the making process, but I'll give you a written description instead: 1. Print the parts that come with an STL file (case, handle, Marshall logo, and logo backplate). 2. Using an aluminum bar and following the two PDF drawings, prepare the two plates (one to hold the four female jacks and the other one to be screwed onto the rear to attach the keyholder to a wall). 3. Paint the case and handle black, the front panel gold, and the logo white (you can smooth out the surfaces with some acetone before painting if you print the parts in ABS for a better-looking result). 4. Screw the four female jacks into the prepared and painted panel. Then slide the panel into place. 5. Cut a piece of women's sock, wrap it around the logo panel, and insert it inside the case from the back. The low clearance between the panel and the inside of the case should hold the sock in place. This panel will prevent the gold jack panel from sliding up. 6. Apply the logo (the two pins of the logo should fit into the holes on the plate, so you won't need any glue). 7. Screw the back panel into place with the four screws. 8. Glue the handle in place with a drop of superglue. Be careful; superglue can turn the plastic white.
