3D Printing Keys for My Enigma Machine. Typewriter Style.

I have made an Enigma machine in my previous project. Now in this project I am designing typewriter style keys for 6mm X 6mm X 8mm tactile keys. I am attaching the stl file if someone wants to directly 3D print them

I started by modeling the basic key design based on the typewriter in 3D builder. Then I started by using the emboss option in the 3D builder and embossed all the alphabets. I then embossed arrow keys by typing "<-". For the stl file attached I did not include "<-" emboss. These keys are 6mm X 6mm X 8mm tactile switch.

I then also added the tubes whose inner hole diameter meet the tactile switch diameter . I will explain that in next step.

I would like to suggest you to use 0.01mm nozzle or use resin 3D printing or other high detailing based 3D printing.

I then started by sanding the 3D printed parts and finishing them. I then used a generic spring generally found in retractable pens. The tubes directly fit the tactile keys pressing part. After fitting the tube I slide a spring in the tube and then the key. Then even we press the key the spring presses and after clicking the button the key jumps back just like old typewriter's.
