It didn't "fit." It wedged into the corners and felt tight. As soon as you applied torque, it slipped because the contact surfaces were mismatched. You got lucky; do not repeat it.
If you remember nothing else from this article, remember this: difference between t20 and tx20
Think of a standard flathead screwdriver vs. a flathead with a hole in the middle. The T20 is the standard; the TX20 is the "keyed" version. It didn't "fit
Clarification Note: In 3D printing communities, "T20" sometimes colloquially refers to the Creality Ender 3 (a cheap FDM printer), while "TX" usually implies higher-end tech. If you are asking about FDM (filament) printers, specifically the , the distinction is price vs. quality. The "TX" in that context would imply an upgraded/modded version, though standard industry naming conventions differ. If you remember nothing else from this article,
Why the difference? The TX20 design eliminates the "stress risers" (sharp internal radii) found in standard Torx. The load is distributed evenly across a flat surface rather than a pointed tip.
