Except for the trigger and some keycaps which use TPU, all other parts are made with PLA or tri-color PETG.

The required bill of materials is relatively complex. The electronics are mainly based on the EJOY32 v3.5 development board and a 74HC165 button expansion board (which can be found in stores selling EJOY32 on Taobao).

Then there are about a dozen 6x6x7 micro switches.

Seven 10x10x9 five-way tactile switches are needed.

Double-sided self-resetting toggle switch MTS-123.

Two rotary potentiometers, 16x2 B103 10K.

One 16x16 small omnidirectional joystick and a 60-degree B103 potentiometer. Be careful, it's easy to buy the wrong size for this omnidirectional joystick.

Then there are some bearings: 8 pieces of 10x15x4 and approximately four pieces of 3x6x2.5.

Then there are springs: about six 0.4x4x6 extension springs. Buy a few extra, as they are easy to lose.

Most screws are M3x10 and M2x10 self-tapping screws; M2x6 screws are also sufficient.

For some areas that are prone to wear, it is recommended to use PETG.

The potentiometer's fixation is quite unconventional. I directly used an approximately 1.2mm BBQ skewer, threading it through the main shaft and into the central hole of the potentiometer. The outside of the potentiometer was hot-glued onto the base. ...Mainly because I wasn't sure what to use at first, so I just designed it casually.
