Geon Trimmer

Geon Trimmer

Fix the fit. Save your keycaps.

The Geon Trimmer is a precision tool designed to calibrate switch stems and keycap mounts when tolerances are just a little too tight. If a switch stem is slightly oversized or causing excessive stress on your keycaps, this tool allows you to carefully adjust the fit for smoother installation and removal.

Rather than cutting material away aggressively, the trimmer works by gradually pushing and refining the stem shape over repeated use—helping maintain structural integrity while improving compatibility.

What you’ll notice:

• Easier keycap installation and removal
• Reduced risk of cracked or overstressed keycaps
• More consistent stem fit across switches
• Greater compatibility between switches and keycaps

3. Use it several times for switches and keycaps that are not used as tools that require adaptation
4. Work vertically and horizontally with the stem
5. The trimmer is a precision tolerance product that is sensitive to impact, so please be careful when using it

Keycap Calibration

1. Keep the keycap leveled during calibration
2. Do not use it vertically
3. If the switch is turned 90 degrees, it must be used vertically
4. Remove the burr by cutting the stem
