Full functional Joystick Keycap : 4-Way Mechanical Keyboard Controller using Number pad.
Transform your mechanical keyboard's number keys into a functional joystick! KeyboaStick integrates four individual switches into one intuitive controller interface. Diagonal operation by pressing two keys simultaneously is also perfectly possible.
Unlike other existing models, this model supports additional buttons. You can press the 5 key in the center of the number pad using the button on the lever.
Almost Real Joystick
While other models may cause unwanted buttons to be pressed if the weight is concentrated on the lever, this model is much more stable thanks to a support in the center that holds up the entire joystick module, and since the buttons are evenly spaced from the center, it provides the closest control feel to a real joystick among all models released so far.
Do you have a Hall effect keyboard?
If you use a keyboard with Hall effect switches, it can be fully utilized for flight simulations and other purposes, just like other analog joysticks.
Key Features
4-Way Integrated Control: Navigate Up, Down, Left, and Right with a simple tilt of the knob.
Additional Button : You can press the number 5 key in the center using the button on the lever.
Intuitive UX: Easy to install on standard number key clusters for immediate use.
Precision Engineering: Optimized pivot structure ensures accurate inputs without key interference.
Printing & Assembly Tips
Recommended Filament: PLA or PETG. (I used PLA)
No Hardware: You can make it without any Hardwares.

Someone who saw this model told me that it could also be helpful to people with disabilities. If my design helps those with physical limitations, it would be truly rewarding. :)
Please Read before printing.
This design is compatible with standard mechanical keycaps. It is not compatible with membrane rubber dome types. It can be installed on few membrane keyboards that follow the standard mechanical keycap design.
This model is inserted using a standard keycap method, so it may detach from the keyboard if handled roughly. This design is not intended to completely replace a joystick; it is intended for simple attachment to the keyboard for use by people who don't have joystick or in locations where a joystick is unavailable.

Assemble Guide
Bond the joints to the floor plate. Be sure to use adhesive.
Combine the lever and the joint. Do not use adhesive.
Insert the connecting post into the center switch (number 5).
Insert the core support.
Insert the lever assembly assembled above into the correct position. Ensure that each switch connects properly.
Connect two parts to make a button.
Insert the button at the top of the lever.
Congratulations. You now have the perfect joystick.
🛠️ For a Perfect Fit: Troubleshooting Guide
The KeyboaStick series is designed to fit standard MX-style switches perfectly. However, depending on your printer’s calibration or filament shrinkage, the fit may occasionally feel loose.
If you experience a loose connection, please try the following simple solutions:
1. Slicer Adjustment (Recommended)
You don't need to change your entire profile. Just adjust this single setting to tighten the fit:
Setting: Hole Horizontal Expansion (in the Precision/Quality tab)
Value: Input -0.05mm or -0.1mm
Effect: This slightly shrinks the inner dimensions of the cross-stem hole, ensuring a tighter grip on the switch.
2. Fine-tune Flow Rate
Increasing the flow rate slightly can help bridge the gap:
Adjustment: Increase your Flow Rate (Extrusion Multiplier) by 1–2% (e.g., from 0.98 to 1.0).
Effect: This thickens the walls of the stem mount, making the connection more secure.
3. Quick Physical Fix (No Re-print Required)
If you've already printed the model and it feels a bit loose:
The Plastic Wrap Trick: Place a tiny piece of thin plastic wrap (clinging film) or a small scrap of paper over the switch stem before pressing the KeyboaStick on. This instantly eliminates any wobble.
Coating: Apply a tiny drop of superglue inside the cross-hole of the KeyboaStick. Let it dry completely before mounting it to create a thin, grippy internal layer. (Warning: Do not mount while wet!)
